Operation
When the control is idle, the output pressure (at F) is limited to the
preset pressure of the valve, irrespective of the supply pressure.
When the lever or pedal is activated, the output pressure (at F) falls in
proportion to the angular position of the control.
•Lever control:
When the lever is in its maximum position (locked), the output
pressure (at F) is zero. The control lever can be unlocked
using the pushbutton (horizontal lever) or the collar (vertical
lever).
•Pedal control:
When the pedal is fully depressed, the output pressure (at F)
is zero.
Installation
Applications
The VB3-002 reverse modulator is a mechanicallycontrolled, three-way, graduated release pressure reducing
valve.
The VB3-002 valve is used for the precision dosing of the
output pressure (at F) proportionally to the control stroke. It
is controlled via a lever or pedal. The lever is usually used to
control the parking brake (spring applied hydraulic release
brake).The pedal is usually used for inching control.

Relay Valve
Operation
When the valve is not operated, the output pressure (X) is limited to the preset max pressure of
the valve independently from the input pressure.
The VB-00E has two principles of operation:
1. Electric actuation
VB-00E has a fixed output pressure preset by the pressure reducing valve. When the
VB-00E is not actuated (understand the electric control = 0) the output (X) is directly
connected to the tank (T) and provide a pressure equal to zero. The SAHR brake is
applied. When the VB-00E is electrically actuated (electric control =1) the output (X) is
connected to the output of the pressure reducing valve: the VB-00E provides the preset
fixed pressure. The SAHR brake is released.
Options
Applications
The VB-00E is a reverse
modulating electrically or
electrically/manually operated
brake valve for Spring Applied
Hydraulically Released
(SAHR) brake. The VB-00E
brake valve is a 3-way / 2position electro-valve and
includes a pressure reducing
valve as well as a selector.
Service
brake
• Electro-hydraulic
27/03/2017
Installation
2. Electric with mechanical actuation
In this configuration, the pressure reducing valve provides an output pressure proportional
to the mechanical command position. When the VB-00E is not actuated (understand the
electric control = 0) the output (X) is directly connected to the tank (T) and provide a
pressure equal to 0. The SAHR brake is applied. When the VB-00E is electrically actuated
(electric control =1) the output (X) is connected to the output of the pressure reducing
valve. Therefore, the VB-00E supplies a precise output pressure inversely proportional to
the mechanical command stroke: the output pressure (X) decreases from a max preset
pressure (control released, brake released) to 0 (control actuated, brake applied).

Operation
When the pedal is at rest ('up' position), the output pressure (at F) is
zero and the brake receptors are connected to the tank (F to T).
When the pedal is depressed, the output pressure (at F) increases
proportionally to the angular displacement of the pedal.
When the pedal is fully depressed, the output pressure (at F) is
limited to the preset pressure of the valve irrespective of the supply
pressure.
Installation
Applications
The VB3-010 modulating brake valve is a
mechanically-controlled, three-way, graduated release pressure
reducing valve.
The VB3-010 valve is used for the precision dosing of the output
pressure (at F) proportionally to the angular displacement of the
pedal, and therefore to the force applied to the pedal. This
provides the feeling of braking.
In a braking circuit, VB3-010 is usually associated with the
VB-100 single-circuit accumulator charging valve (or a VB-200
dual-circuit accumulator charging valve if the VB3-010 is also
associated with a VB3-002 emergency / parking brake valve).

Operation
When the pedal is at rest ('up' position), the output pressures (at F1
and F2) are zero and the brake receptors are connected to the tank (F1
and F2 to T).
When the pedal is depressed, the output pressures (at F1 and F2)
increase proportionally to the angular displacement of the pedal. The
output pressures (at F1 and F2) can be equal or different according to
a ratio F2/F1 = 0.64 (VB-0E0) or 0.44 (VB-0F0).
When the pedal is fully depressed, the output pressures (at F1 and
F2) are limited to the preset pressures of the valve irrespective of the
supply pressure.
The pressures at F1 and F2 are strictly independent. A failure in one
of the circuits does not affect the operation of the other circuit.
Installation
Applications
The VB-020 service brake valve (VB-0E0 and VB-0F0) is a
mechanically-controlled, three-way, graduated release double
pressure reducing valve.
The VB-020 (VB-0E0 and VB-0F0) valve provides precisely
controlled output pressures (at F1 and F2) proportional to the
pedal stroke and therefore to the force applied to the pedal.
This provides the feeling of braking. In a braking circuit, VB020 (VB-0E0 and VB-0F0) is usually associated with the VB200 dual-circuit accumulator charging valve.

POCLAIN HYDRAULICS
Options
Operation
The VB3-012 valve controls two independent pressures via a
pedal. One pressure is for automotive pump control, and the other
is for service braking control.
When the operator presses the pedal, VB3-012 supplies a
pressure inversely proportional to the angular displacement of the
pedal to control the hydraulic pump.
If more braking is required, the operator continues to press the
pedal.
VB3-012 then supplies an output pressure to the service brake in
proportion to the angular displacement of the pedal.
Installation
Applications
The VB3-012 brake control is a single-circuit braking assembly that
combines:
• The VB3-002 emergency / parking brake valve, which supplies an
output pressure to control the automotive pump (inching),
• The VB3-010 service brake valve, which supplies a pressure to
control the service braking.

• VB3-002 can be used for VB-022*
Output pressures F1 and F2 can be equal (VB-022) or different
according to a ratio F2/F1 = 0.64 (VB-0E2) or 0.44 (VB-0F2).
• Two-step braking:
When the operator presses the pedal, the VB-022 supplies a
pressure that is inversely proportional to the angular
displacement of the pedal, to control the hydraulic pump.
If more braking is required, the operator continues to press the
pedal. VB-022 then supplies an output pressure to the service
brakes in proportion to the angular displacement of the pedal.
• Simultaneous braking:
VB-022, VB-0E2 and VB-0F2 simultaneously control the pump
(hydrostatic braking) and the service braking (mechanical
braking) for more aggressive dynamic braking.
Options
• The VB-002 emergency / parking brake valve, which provides an
output pressure to control the automotive pump (inching),
• The VB-020 service brake valve, which provides two output
pressures, F1 and F2, for independent braking circuits.
Operation
VB-022 controls three independent pressures via a pedal. One
pressure controls the automotive pump, and the other two
pressures control the service braking.

Pressure reducing valve
Selector right pedal
27/03/2017
Options
Operation
VB-0B0 performs two types of braking:
- Left/right directional braking in field mode.
- Braking with equal power distribution in road mode.
• Field mode:
VB-0B0 provides steering assistance for turning. In field mode, the
two pedals are actuated independently. When the operator
depresses either pedal, the pressure reducer and the selector
associated with this pedal are actuated. VB-0B0 supplies a
graduated release braking pressure exclusively to the service
brakes associated with this pedal.
• Road mode:
In road mode, the two pedals are mechanically linked. When the
operator depresses one pedal, the other one is driven, and so both
selectors are actuated together. The VB-0B0 valve supplies an
identical pressure to both brakes, proportional to the stroke of the
pedals.
Installation
Applications
The VB-0B0 valve is a single circuit brake valve that provides
dynamic service braking in road mode and steering-assist
braking in field mode.
VB-0B0 is actuated by two pedals, and supplies two independent
brakes on rear axle. The VB-0B0 valve combines the following
components in a single unit:
• A pressure reducer that supplies an output pressure
proportional to the pedal stroke.
• Two circuit selectors, each one associated with one of the
pedals of the VB-0B0.

Options
Operation
VB-0D0 performs two types of braking:
- Left/right directional braking in field mode.
- Braking with equal power distribution in road mode.
• Field mode:
VB-0D0 provides steering assistance for turning. In field mode, the
two pedals are actuated independently. When the operator
depresses either pedal, the pressure reducers and the selector
associated with this pedal are actuated. VB-0D0 supplies a
graduated release braking pressure exclusively to the service
brakes associated with this pedal.
• Road mode:
In road mode, the two pedals are mechanically linked. When the
operator depresses one pedal, the other one is driven, and so both
selectors are actuated together. The VB-0D0 valve supplies an
identical pressure to all brakes, proportional to the stroke of the
pedals.Γ
Installation
Applications
The VB-0D0 valve is a double circuit brake valve that provides
dynamic service braking in road mode and steering-assist
braking in field mode.
Standard VB-0D0 product has dual slope characteristic and
improved watertightness.
VB-0D0 is actuated by two pedals, and supplies three
independent brakes (two on the rear axle and one in the front
axle).
The VB-0D0 valve combines the following components in a
single unit:
• A pressure reducers that supplie an output pressure
proportional to the pedal stroke.
• Two circuit selectors, each one associated with one of
the pedals of the VB-0D0.

Operation
During the accumulator charging phase, the built-in divider taps a
constant flow from the valve supply flow and diverts it to the
accumulator.
When the accumulator reaches maximum (cut-out) pressure,
charging stops, and the entire supply flow is directed to output S
(auxiliary circuit or tank return).
Each time the operator actuates the pedal, the pressure in the
accumulator drops. When minimum (cut-in) pressure is reached, the
valve again charges the accumulator until it reaches cut-out pressure,
and so on.

Operation
During the accumulator charging phase, the built-in divider taps a
constant flow from the valve supply flow and diverts it to the
accumulator. When the accumulator reaches maximum (cut-out)
pressure, charging stops, and the entire supply flow is directed to
output S (auxiliary circuit or tank return).
Each time the operator actuates the pedal, the pressure in the
accumulator drops. When minimum (cut-in) pressure is reached, the
valve recharges the accumulator to cut-out pressure, and so on.
The modulating brake valve is a mechanically-controlled, three-way,
graduated release pressure reducing valve.
It is used for the precision dosing of the output pressure (at F)
proportionally to the angular displacement of the pedal, and therefore
to the force applied to the pedal. This provides the feeling of braking.
When the pedal is at rest ('up' position), the output pressure (at F) is
zero and the brake receptors are connected to the tank (F to T).
When the pedal is depressed, the output pressure (at F) increases
proportionally to the angular displacement of the pedal. When the
pedal is fully depressed, the output pressure (at F) is limited to the
preset pressure of the valve irrespective of the supply pressure.
Installation
Applications
The VB-110 braking assembly contains the following
components in a single manifold:
• A single-circuit accumulator charging valve,
• A mechanically controlled single-circuit service brake valve.
The incorporation of these functions in a compact unit reduces
the risk of leaks and makes the overall size more compact.

Operation
During the accumulator charging phase, the built-in divider taps a
constant flow from the valve supply flow and diverts it to the
accumulator. When the accumulator reaches maximum (cut-out)
pressure, charging stops, and the entire supply flow is directed to
output S (auxiliary circuit or tank return).
Each time the operator actuates the pedal, the pressure in the
accumulator drops. When minimum (cut-in) pressure is reached, the
valve recharges the accumulator to cut-out pressure, and so on.
The service brake valve is a mechanically-controlled, three-way,
graduated release dual pressure reducing valve. It is used for the
precision dosing of the output pressures (at F1 and F2) proportionally
to the angular displacement of the pedal, and therefore to the force
applied to the pedal. This provides the feeling of braking. When the
pedal is at rest ('up' position), the output pressures (at F1 and F2) are
zero and the brake receptors are connected to the tank (F1 and F2 to
T).
When the pedal is depressed, the output pressures (at F1 and F2)
increase proportionally to the angular displacement of the pedal.
When the pedal is fully depressed, the output pressures (at F1 and
F2) are limited to the preset pressure of the valve irrespective of the
supply pressure. When a failure occurs in one of the braking circuits,
the other circuit is immediately isolated by its safety valve. The circuit
that remains operative can then be used as an emergency brake
thanks to the energy stored in its accumulator.
Options
Applications
The Poclain Hydraulics VB-220 braking assembly contains the
following components in a single manifold:
• A dual-circuit accumulator charging valve,
• A mechanically controlled dual-circuit service brake valve,
• Two isolating valves for the braking circuits.
The output pressures (at F1 and F2), for the braking circuits,
can be equal or different according to a ratio F2/F1 = 0.64
(VB-2E0) or 0.44 (VB-2F0).

accumulator drops. When minimum (cut-in) pressure is reached, the
valve recharges the accumulator to cut-out pressure, and so on.
The service brake valve is a mechanically-controlled, three-way,
graduated release dual pressure reducing valve. It is used for the
precision dosing of the output pressures (at F1 and F2) proportionally
to the angular displacement of the pedal, and therefore to the force
applied to the pedal. This provides the feeling of braking. When the
pedal is at rest ('up' position), the output pressures (at F1 and F2) are
zero and the brake receptors are connected to the tank (F1 and F2 to
T).
When the pedal is depressed, the output pressures (at F1 and F2)
increase proportionally to the angular displacement of the pedal.
When the pedal is fully depressed, the output pressures (at F1 and
F2) are limited to the preset pressure of the valve irrespective of the
supply pressure. When a failure occurs in one of the braking circuits,
the other circuit is immediately isolated by its safety valve. The circuit
that remains operative can then be used as an emergency brake
thanks to the energy stored in its accumulator.

Relay Valve
Operation
During the accumulator charging phase, the built-in divider taps a
constant flow from the valve supply flow and diverts it to the
accumulators. When the accumulators reach maximum (cut-out)
pressure, charging stops, and the entire supply flow is directed to
output S (auxiliary circuit or tank return).
Each time the operator actuates the pedal, the pressure in the
accumulator drops. When minimum (cut-in) pressure is reached in at
least one accumulator, the valve recharges the accumulators to cutout pressure, and so on.
The service brake valve is a mechanically-controlled, three-way,
graduated release dual pressure reducing valve. It is used for the
precision dosing of the output pressures (at F1 and F2) proportionally
to the angular displacement of the pedal, and therefore to the force
applied to the pedal. This provides the feeling of braking. When the
pedal is at rest ('up' position), the output pressures (at F1 and F2) are
zero and the brake receptors are connected to the tank (F1 and F2 to
T). When the pedal is depressed, the output pressures (at F1 and F2)
increase proportionally to the angular displacement of the pedal.
When the pedal is fully depressed, the output pressures (at F1 and
F2) are limited to the preset pressure of the valve irrespective of the
supply pressure.
When a failure occurs in one of the braking circuits, the other circuit is
immediately isolated by its safety valve. The circuit that remains
operative can then be used as an emergency brake thanks to the
energy stored in its accumulator. The parking brake valve has on/off
solenoid control.

VS
• 70 l/min [18.5 GPM]
Operation
VS Valve is designed for
applications with long brake
lines or very large brake
cylinder volume, requiring
high flow 70 l/min [18.5 GPM].
VS valve is normally used with full power brake as "Relay Valve" and with parking brake as
"Quick Return Valve".
VS Valve is a 3-way valve
with an external hydraulic
control. It supplies and drains
high volume brakes by
connecting accumulator to
service brakes on large
machines.
VS as Relay Valve:
Control pressure (F1 & F2) is supplied to the VS valve proportionaly to brake pedal angle on full
power brake valve (VB-220). VS relay valve provides high flow directly from the accumulators
(A1 & A2) to the brakes, proportional to the control pressure, i.e. directly proportional to the
pedal position. The braking is progressive. As soon as brake pedal is released, VS transfers oil
from brakes to the tank (T).
• External hydraulic pilot.
• Located between the accumulator(s) and the brake(s).
• Controlled and used with a modulating brake valve.

Isolating ball valves
In the event of failure of one of the braking circuits, this function acts in a similar way to isolating spool valves by keeping an energy
reserve in the accumulator of the non-faulty circuit (limited reserve in the accumulator) and does not maintain pressure in the S line
when a circuit has failed (if the steering is fed by the S port of the valve, choose spool valves).

Installation
For certain applications, the braking sensation, the ergonomics of the pedal board,
and the overall behavior of the braked vehicle require a special braking curve. The
first part, with its gradual slope, provides gentle, progressive braking to slow the
vehicle. The second part, with a steeper slope, provides a braking finish that is
progressive but firmer, for emergency braking. According to the shape of the pedal,
the user's impression can be similar to a master cylinder. Please ask us about the
available pressures.
8 Pressure sensor
The sensor (refer to mobile electronics catalog No. A01888C) is installed on the MF port (single-circuit valves) or the MF1 port (dualcircuit valve). It sends a pressure signal to the electronic circuit in the form of an electrical signal that is proportional to the pressure. It
can also replace the MF pressure switch in its stop light control function.

Take the following precautions for making up the tubes:
• After cutting to length, cold bending and crimping, the tubes must be carefully deburred, rinsed with oil
and blown before connection.
• After welding or bending, the tubes must be etched (solution based on sulfuric acid) then rinsed with oil
and neutralized (solution based on sodium hydroxide).
• The connections, threaded plugs, etc. must be deburred and cleaned before assembly.
• If assembly is not done immediately, seal the ports with plugs.
Relay Valve
Comply with the connection directions given by the manufacturers for each part: function and marking of the
ports, types of connections, diameters, types of lines (flexible or rigid), etc.
Rigid Tubes
For high-pressure pipes, only use unwelded cold-drawn steel pipes.

General Recommendations
Poclain Hydraulics recommends the use of hydraulic fluids defined by the ISO 12922 and ISO 6743-4 standards.
For temperate climates, the following types are recommended.
• HM 46 or HM 48 for fixed installations.
• HV 46 or HV 68 for mobile installations.
• HEES 46 for mobile installations.
These specifications correspond to category 91H of the CETOP standard, parts 1, 2 and 3 of the DIN 51524
standard, and grades VG32, VG 46 and VG68 of the ISO 6743-4 standards.
T
It is also possible to use ATF, HD, HFB, HFC or HFD type hydraulic fluid upon Poclain Hydraulics specific
approval of the components’ operating conditions.
Standardized designations for the fluids
• HM : Mineral fluids having specific antioxidant, anticorrosion and antiwear properties (HLP equivalent to
DIN 51524 parts 1 and 2).
• HV : HM mineral fluids providing improved temperature and viscosity properties (DIN 51524 part 3).
• HEES :Biodegradable fluids based on organic esters.
Class 32 (ISO VG 32) : Viscosity of 32 cSt at 40°C.
Class 46 (ISO VG 46) : Viscosity of 46 cSt at 40°C.
Class 68 (ISO VG 68) : Viscosity of 68 cSt at 40°C.
Viscosity must always be between 9 and 500 cSt. If not, check the appropriateness of the cooling circuit,
the design, or the grade of oil.
For all applications outside these limits, please consult your Poclain Hydraulics Application Engineer.

Zone E

Zone B
Zone of maximum efficiency.
In this zone, temperature variations have a weak effect on the response time, efficiency and life expectancy of
the components.
Poclain Hydraulics components can operate at all speeds, pressures and powers specified in their technical
documentation.
High speeds can lead to vibrations and drops in mechanical efficiency. The booster pump can cavitate if the
intake conditions are too tight but without risk for the system as long as the pump remains boosted.
The Poclain Hydraulics components can operate at the pressures specified in their documentation but it is not
advisable to use the pumps at full displacement.
In a translation circuit, a rapid rise in the pump speed from zone B is allowed, but ordering the translation when
the temperature has reached zone A is recommended.
The efficiency is less and the use of effective antiwear additives is required.
The Poclain hydraulics components can temporarily operate at a power under 20 to 50% of that stated in the
technical documentation, or during 20% of the operating time at the stated power.
The stated restrictions for zone B likewise apply to zone D.
Further, the pumps must startup at low speed and no displacement. They must not be used in their normal
operating conditions as long as the booster pressure has not stabilized and the hydraulic fluid temperature in
the reservoir has not come up to zone B.
The efficiency is reduced and the risk of wear on the pump and hydraulic fluid is increased.
The system can operate in zone E at low-pressure and during short periods.
The temperature of the hydraulic fluid in the power circuit must not be more than 10°C above the temperature of
the hydraulic fluid in the reservoir, and must not be more than 20°C warmer than the hydraulic fluid in the
components’ cases.

Water Content
The ISO 12922 standard calls for a water content d 0.05%.
Poclain Hydraulics components tolerate up to 0.1%.
Checking Water Content
Visual Inspection
• The oil appears cloudy once it has a water concentration greater than or equal to 1%.
We suggest two possible verification methods:
1- Quick Elementary Check
• The “crackle test.”
Step
1
Make a small cup using household aluminum foil.
2
Put a drop of oil to test in
the bottom of the cup.
Action
Step
3
Heat it by placing it
over a flame using
tongs.
4
If bubbles appear, the
water content of the fluid
exceeds 0.05%.
Action
If bubbles do not appear,
the water content in the
fluid is less than 0.05%.
2- Laboratory analysis
To determine the exact water content of the fluid, we recommend a laboratory analysis.
Poclain Hydraulics performs laboratory analyses of water content in fluids. Contact us for further information.
Decontamination and Filtration
The life of hydraulic components is lengthened when the contamination level is low.
94
27/03/2017
VB Brake Valves
The hydraulic fluid must be maintained at ISO standard 4406 -1999 decontamination level 18/16/13 (class 7 from NAS 1638) using a filter.

New fluid is generally of lower quality than our requirements.
Poclain Hydraulics asks its customers to fill or adjust the levels in the reservoirs in a clean environment using a pump and
filter.
Return line
It is ESSENTIAL to connect the valve return line directly to the tank.
Options
Any counterpressure on the return line can cause premature
brake wear without any use of the pedal.
Accumulators
Installation
- Select accumulators whose maximum allowable pressure is compatible with the valve pressures.
- Accumulator charging valve: any pressure on S (higher than the cut-out pressure) ends up in the accumulator(s) of the braking circuit.

Mounting
The mounting is defined for each valve type, and depends on the type of mechanical control selected.
When the valve is installed, the pedal must not be obstructed
during its stroke.
The valve bodies must never touch other components (min.
