Model 570, 571, 573 Control Valve
Operation, Parts, and Instruction Manual
UNPACKING VALVE FROM SHIPPING
CONTAINER
Check the packing list against materials received, while
unpacking the valve. The Packing List describes valve and
accessories in each shipping container.
When preparing valves and actuators for lifting, be sure to use
certified lifting equipment and proper rigging. Position any
lifting straps to avoid damage to the tubing and mounted
accessories.
INSTALLATION
WARNING
Refer to the General and Scope sections of this
Manual (See Page 2) prior to beginning Installation.
Before installing these valves, be sure to inspect the flange
mating surfaces on both the valve and the pipeline flanges.
Clean dirt, welding chips, scale or other foreign material from
the line and flange surfaces. Check the pipeline flanges for
alignment and look for signs of gasket leakage through the line
flanges, make repairs if necessary.
The Model 570 requires the use of long studs that span the
length of the valve and through both line flanges. The body
casting is designed to utilize the long studs to assist in
centering the valve in the line. Models 571 & 573 use shorter
studs to connect the valve flanges with the line flanges,
the studs do not center the valve in the pipeline.
CAUTION
Only well trained experienced technicians should
perform these procedures. Be sure to use safe work
practices and lockout procedures. Always be aware
of the hazards of spring-loaded actuators. Be sure
that they are in the failed (de-energized) position
before performing any maintenance procedure.
These valves have dangerous pinch points. Never
put your hands inside the valve unless you are
certain that the ball cannot rotate. Use safe work
practices and lock out procedures when isolating
valves and actuators. Always be aware of flammable
instrument gas.
1
Install the valve with flow through the valve in the direction
as indicated by the arrow on the valve body (standard flow
direction has the seal protector ring (Key 10) facing
upstream). The valve assembly may be installed in any
position unless limited by vibration considerations, See
Figure 6. NOTE: excessive wear to the valve may be
caused if the valve is installed with the drive shaft
(Key 16) in a vertical orientation.
WARNING
Keep hands, hair and clothing away from all moving
parts when operating the valve. Serious injury can
result from failure to do so.
Model 570 Installation
(Refer to Figures 2 and 3, and Tables 7, 8, 9, and 10 for
flange stud (Key 32) dimensions)
1
Coat the threads of two flange studs with anti-seize
lubricant and install them into the flanges before
placing the valve body. The two studs should be placed
appropriately to help center the bottom of the valve
body, See Figure 3.
2
Set the appropriate line gaskets in place.
3
Insert the valve into line centering the bottom of the
valve body between the two studs installed in Step 1.
Lubricate the remaining studs with anti-seize
compound and install them. Make sure the valve
is properly centered between the pipeline flanges and
then tighten the flange studs evenly in a criss-cross
pattern to the correct torque specifications.
Models 571 & 573 Installation
(Refer to Figures 2 and 3, and Tables 7, 8, 9, and 10 for
flange stud (Key 32) dimensions)
NOTE
Longer flange studs are needed for the seal
protector ring (Key 10) side of the valve. DO NOT
use standard length studs for the seal protector
side of the valve, see Table 8.
1
Lubricate the flange studs with anti-seize compound
and have them ready to hold the valve in line.
2
Set the appropriate line gaskets in place.

Operation, Parts, and Instruction Manual
INSTALLATION (Continued)
Models 571 & 573 Installation (Continued)
3
Insert the valve in line and make sure the valve is
properly centered between the pipeline flanges.
Tighten all the flange studs and nuts evenly in a crisscross pattern to the correct torque specifications.
2
Check for process fluid leakage to the atmosphere through
the packing and (if equipped) any NPT connection.
3
Examine the valve for damage caused by corrosive fumes
or process drippings.
4
Clean the valve and repaint areas of severe oxidation.
6
Ensure all accessories, mounting brackets and fasteners
are secure.
7
Clean any dirt and foreign material from the stem.
Air Piping
Standard actuators are designed to accept a 1/4” (6 mm) NPT
connection. Use 3/8” OD tubing (or equivalent) for all air
lines. Always follow good piping practices when installing
piping or tubing, install all required line vents, valves,
drains, seals, and filters. For more information refer to the
appropriate actuator instruction manual for your product.
WARNING
Property damage, environmental harm, and
personal injury can result from the use of supply
gas other than clean, non-corrosive, oil and
moisture free air. Do not exceed the supply
pressure indicated on the serial plate located on
the yoke of the actuator.
PERIODIC INSPECTION
CAUTION
Use safe work practices and lock out procedures
when isolating valves and actuators! Always be
aware of flammable instrument gas!
1
Avoid personal injury from sudden release of process
pressure! Before performing any maintenance operation:
A
Disconnect any power supply media lines providing
air / gas pressure, electric power, or a control signal
to the actuator. Ensure the actuator cannot suddenly
operate the valve.
B
Isolate the valve from process pressure with bypass
valves or completely shut off the process. Relieve
process pressure, and drain the process fluid from
the up and down stream of the valve.
C
Vent the pneumatic actuator loading pressure and
relieve any actuator spring preload.
D
Use Safety lock-out procedures to be sure that the
above provisions stay in effect while you complete
the work on your equipment.
PACKING MAINTENANCE
If the packing is leaking, and tightening the packing flange
does not stop the leak, then it is recommended that you
remove the valve from the line. Refer to Valve Disassembly /
Packing Removal for maintenance instructions. For live loaded
packing, refer to the live loaded packing instructions for proper
adjustment procedures.
DISASSEMBLY
CAUTION
Only well trained experienced technicians should
perform these procedures. Be sure to use safe work
practices and lockout procedures. Always be aware
of the hazards of spring-loaded actuators. Be sure
that they are in the failed (de-energized) position
before performing any maintenance procedure.
These valves have dangerous pinch points.
Never put your hands inside the valve unless
you are certain that the ball cannot rotate.
1
Isolate the valve from the process by completely
shutting off the process pressure or use bypass valves if
necessary. Drain the process fluid from upstream and
downstream of the valve.
2
Disconnect any power supply media lines providing air /
gas pressure, electric power, or a control signal to the
actuator. Isolate and bleed off any instrument gas from
the actuator and instruments. Ensure the actuator cannot
suddenly operate the valve.
CAUTION
Use safe work practices and lock out procedures
when isolating valves and actuators! Always be
aware of flammable instrument gas!

Operation, Parts, and Instruction Manual
DISASSEMBLY (Continued)
3
1
Remove the packing nuts (Key 27), note any corrosion
or roughness in the threads. Remove the packing
follower (Key 23) by sliding it over the drive shaft
(Key 16).
Secure the valve and actuator assembly and remove them
from the pipeline by removing the flange studs (Key 32).
Valve / Actuator Disassembly
1
Replacing the ball seal can be accomplished without
removing the actuator. Place the valve assembly on a
flat work surface that can support the assembly
weight, the valve seal protector ring (Key 10) should
be facing up. Relieve any actuator spring preload and
refer to the appropriate actuator instruction manual
for actuator disassembly instructions.
2
Take note of the ball position relative to the
actuator lever where the spline of the shaft goes
through. This will assure proper ball position during
reassembly. A digital camera works well for this. You
can remove the travel indicator arrow, (DFR 026 and
DFR 047) or the cover plate, (DFR 070, DFR 156 and
DFR 220) from the actuator and mark the shaft and
lever with a punch or take a digital picture showing
the ball position and the lever position. For Dyna-Flo
Model DFR 026 actuators there is no clamp on the
lever. For the DFR 047, DFR 070, DFR 156 and the DFR
220 you will have to remove the cover and loosen the
clamp on the lever.
3
Remove the actuator mounting bolt (Key 30) and slide
the valve body assembly from the actuator. This may
require the use of a pry bar between the body and the
actuator mounting pad. The lever on the DFR 070, DFR
156 and DFR 220 will sometimes bind when trying to
remove the valve body assembly. A wedge driven into
the slot in the lever will help to loosen the clamp on
the lever. CAUTION: Using a hammer to drive the
actuator off of the valve shaft can seriously damage
the valve.
NOTE
Valve shaft packing (Key 22) may be removed
without removing the drive shaft (Key 16) from
the valve however it is easier to remove the
packing and inspect the valve shaft and packing
bore when the drive shaft is removed. Refer to
Ball / Shaft Removal for drive shaft disassembly
instructions.
2
Using a mechanics pick set or wire hook, remove the
packing box parts (Keys 21 & 22) from the packing
bore. Be extremely cautious not to damage the drive
shaft or the packing bore while removing packing as
this will cause new packing to leak.
3
Inspect all packing parts, drive shaft, and packing bore
for damage, polish or replace as necessary. Refer to
Assembly / Packing for packing assembly instructions.
Ball Seal Removal
NOTE
During seal removal, the valve actuator may
remain mounted to the valve body.
1
Rotate the valve ball (Key 3) to the open position.
For PTFE Composition Ball Seals
WARNING
To Avoid personal injury and property damage
use caution when separating the actuator from
the valve body, during removal the valve ball
may rotate in the body.
A
Remove the seal protector ring screws (Key 12)
and seal protector clips (Key 11). Carefully
remove the seal protector ring (Key 10) and
gasket (Key 9).
B
Remove the seal (Key 5) from the valve body.
For 2 inch valves remove the back-up ring
(Key 4) as well.
C
Clean and inspect all seating, sealing, and gasket
surfaces for damage. If there is excessive wear
or damage to the seal ring, check the valve ball
(Key 3) for damage in corresponding areas. It is
also a good opportunity to inspect the flange
gasket surfaces for damage while the valve is
out of line.
Packing Removal
For live loaded packing, refer to the Live Loaded Packing
instruction manual (P-LLPR) for assembly instructions.

Ball Seal Removal (Continued)
For 2 Inch Valves
For Metal Ball Seals
A
Remove the seal protector ring screws (Key 12A)
and seal protector clips (Key 11A). Carefully
remove the seal protector ring (Key 10) and
gasket (Key 9). NOTE: Caution when
removing the seal protector ring the metal ball
seal can fall out and damage itself or the ball.
B
Carefully remove the metal ball seal (Key 6) by
pushing it away from the flange gasket side of the
seal protector ring.
C
Remove the wave spring (Key 8) and the radial
seal (Key 7) from the seal protector ring.
D
Clean and inspect all seating, sealing, and gasket
surfaces for damage. It is also a good
opportunity to inspect the flange gasket surfaces
for damage while the valve is out of line.
1
Mark the shaft to show the orientation of the ball
before beginning disassembly, this will help to
re-install the shaft properly on reassembly. It is
possible to install the valve shaft 180 degrees out of
alignment which will make it difficult to mount the
actuator.
2
Rotate the ball to the ‘open’ position and locate the
smaller of the pin holes on the ball (see Figure 7).
To keep the ball and shaft in proper position it may
be necessary to support the ball using a wood or soft
block during disassembly. Using a 3/16” pin punch,
drive the shaft pin (Key 15) out of the ball / drive shaft
(Key 16) connection by driving the shaft pin out the
larger side of the pin hole.
3
Using the same 3/16” pin punch, remove the follower
shaft pin (Key 14) from the valve ball / follower shaft
(Key 13) connection.
4
Remove the pipe plug (Key 28) and drive the follower
shaft into the ball towards the drive shaft. If the drive
shaft cannot be pulled out by hand, continue to drive
the follower shaft into the drive shaft until it loosens.
Being careful not to allow the ball to drop, pull the
drive shaft from the valve body through the actuator
mounting end of the valve.
5
Remove and inspect the valve ball for damage. Inspect
the valve shafts and valve body for damage as well.
Ball / Shaft and Bearing Removal
CAUTION
If the bearings (Key 20) require removal special
tooling may be required. In most cases the bearings
can be removed with a standard punch, a standard
punch may also damage the bearings. If the bearings
are to be reused, see Figures 10 & 11 and Table 12
for drawings and information on bearing removal
tools that will not damage the bearings.
NOTE
Before the bearings can be removed from the valve
both the drive shaft (Key 16) and follower shaft
(Key 13) must be removed from the valve body
(Key 1). The ball seals must be removed prior to
removing the valve ball and valve shafts.
The follower shaft to ball connection uses a follower shaft pin
(key 14) in a stepped hole and can only be installed and
removed in one direction. (See Figure 7)
For 3 through 12 Inch Valves
1
Mark the shaft to show the orientation of the ball
before beginning disassembly, this will help to
re-install the shaft properly on reassembly. It is
possible to install the valve shaft 180 degrees out of
alignment which will make it difficult to mount the

CAUTION
To avoid dropping and damaging the valve ball
(Key 3) when inserting the ball into the valve body
(Key 1) it may be necessary to support the ball
using a wood or soft block during assembly.
NOTE
For 3 through 12 inch valves the valve shaft / valve
ball connection is made using a flat key (Key 18)
and set screws (Key 17), see Figure 9. The shaft
/ ball connection is factory set, but if the shaft or key
needs to be replaced or if the connection is loose it
will need to be reset prior to assembly. See Page 27.
1
For valve sizes 3 through 12, set the drive shaft to ball
connection prior to assembly. Refer to Page 27 for
instructions to set the shaft / ball connection.
2
Carefully insert the valve ball into the valve body.
Insert the follower shaft (Key 13) through the valve
body and into the valve ball.
3
Align the pin hole of the follower shaft with the follower
shaft pin hole on the valve ball. Insert the follower
shaft pin (Key 14) into the ball / follower shaft assembly.
4
Install the drive shaft (Key 16) through the bearing
and into the valve ball. Set the valve shaft to the
original orientation as per Step 1 of Ball / Shaft and
Bearing Removal. Install the shaft key (Key 18) or
shaft pin (Key 15) for 2” valves, and refer to Pages
25, 26, and 27 for shaft pin and shaft key installation
instructions.
5
With the follower shaft pins and flat key installed
beneath the hole on the surface of the ball ear, stake
the pins and/or flat key on both the drive shaft and
follower shaft using a center punch. See Pages 25 - 27
for further instructions.
NOTE
To prevent trapping air when installing packing
rings it is recommended that packing rings be
installed one at a time. Do not force packing
rings below the chamfer of the packing bore
before adding another ring. See Figure 4.
2
Install the packing parts as shown in Figure 14. For
PTFE packing, lubricate the packing with a siliconebased lubricant.
3
Install the packing follower (Key 23).
4
Thread the packing nuts (Key 27) onto the packing
studs (Key 26) and tighten them in an alternating
pattern until the packing follower is secured. The
packing nuts should be tightened enough to stop
leakage under operating conditions.
Ball Seal Assembly
1
Have all parts and seal surfaces cleaned and inspected
prior to assembly. Refer to Disassembly section for
inspection procedures.
2
Rotate the ball (Key 3) to the closed position. Inspect
the position of the ball along the axis of the shaft
(Key 16). The ball should be no more than 0.005
inches (0.13 mm) off the center line. It may be
necessary to use a feeler gauge between the
clearance angles just below where the ball seal sits,
using a feeler gage the maximum difference would be
0.010 inches (0.254 mm). For 2 inch valves the
back-up ring (Key 4) will need to be installed to check
the position of the ball. If the ball is not centered it
may be due to some wear on the ears of the ball or
the thrust face of the bearings, re-inspect all surfaces
for damage.

Model 570, 571, 573 Control Valve
Operation, Parts, and Instruction Manual
DRIVE SHAFT PIN
The 2 inch model 570 uses a 1/4” diameter shaft pin (Key 15) to connect the drive shaft to the ball that is precisely fitted to
easily insert into the ball/shaft by hand or with light tapping by a hammer and punch. New ball/shaft assemblies will have the
pins inserted loose for easy removal prior to installing into the valve. Use a 1/8 pin punch to remove the pin.
CAUTION
Because the drive shaft pin hole is stepped, the pin can only be removed from one direction. Once the new Ball,
Shaft and Pin is installed, the pin hole must be staked to prevent the pin from coming out during operation.
Because the pin can only be inserted from one direction, staking the side that the pin is inserted from will prevent
the pin from falling out.
NOTE
Deforming the edges of the hole without properly supporting the ball could result in damage. It is advisable to
install the follower shaft into the valve and to carefully suppost the ball before staking the edge of the hole on the
drive shaft to prevent damage from occuring to the ball / shaft assembly. See next page for Follower Shaft Pin
assembly.
NOTE
The 2 inch 570 ball/shaft is sold only as an assembled
matched set and must be replaced as an assembly.
Figure 17 Use a pointed center
punch to stake the edge of the hole
as illustrated to the left. In the
illustration to the left a shop rag is
used to hold the ball in the proper
position for staking. Be careful not
to damage the machined surfaces of
the ball or body.
Staked Pin Photo and
Follower Shaft Pin Instructions
available on Page 26.
NOTE
The ball to shaft connection is set prior to assembly. For instructions on removal of the ball,shaft and key refer to
Page 11.

FOLLOWER SHAFT PIN
The 2 inch 570 follower shaft (Key 13) also uses a straight pin to retain the follower shaft in position. Early designs used a
non-stepped 3/16” diameter hole in the ball and a longer (1-1/4”) pin which is deformed to allow the pin to tighten in the hole.
Later designs use stepped pin hole similar to the drive end. When using a longer (1-1/4” long) pin, you must assure the pin is
deformed to allow the pin to tighten in the hole when installed. When using the shorter (1-1/16” long) pin, the pin hole must be
staked, as illustrated below, to prevent the pin from coming out during use. Install the follower shaft. For non-stepped holes you
will need to stake both sides. Stake the first side, then insert the pin, then stake the second side. For stepped holes insert the pin
and stake the large side only.

3 THROUGHT 12 INCH BALL TO SHAFT ASSEMBLY INSTRUCTIONS
These instructions outline the recommended procedure for assembly and setting of the ball to shaft connection. Use these
instructions when setting or re-setting the ball to shaft connection or when replacing either the ball or shaft. The ball to shaft
connection is set prior to assembly. For instructions on removal of the ball, shaft and key refer to Page 11. The connection design
allows for adjustment of a shaft key using setscrews. As the set screws are adjusted clockwise the shaft key is forced against a
taper which allows for easy field rotation play in the ball to shaft connection, and when set properly allows for easy field removal.

Using protective covers on the
vise jaws to protect against
damage to the shaft. Place the
shaft in a vise with flat facing up
as shown.
Rotate the ball and shaft as shown
and tighten the setscrews until all
rotational play is removed. Do not
over tighten or removal wil be
difficult.
Slide the ball onto the shaft
and insert the flat key (flat
