“Hydrocontrol VTR/VPR”
Bronze double regulating and
commissioning valves PN 16/PN 25
Technical information
Function:
Oventrop double regulating and commissioning valves are
installed in the pipework of hot water central heating and cooling
systems and serve to achieve a hydronic balance between the
various circuits of the system.
The balance is achieved by a presetting with memory lock.
The required presetting values can be obtained from the flow
charts. All intermediate values are infinitely adjustable.
The selected presetting can be read off two scales (basic scale
and fine adjustment scale, see illustration presetting). The
Oventrop double regulating and commissioning valves have
2 threaded ports for fill and drain ball valves or pressure test
points for the measurement of differential pressure.
The double regulating and commissioning valves may be installed
in either the supply or the return pipe.
When installing the valve it must be ensured that the direction of
flow conforms to the direction of the arrow on the valve body and
that the valve is installed with a minimum of L = 3 x Ø of straight
pipe at the valve inlet and of L = 2 x Ø of straight pipe at the valve
outlet.
“Hydrocontrol VTR”
The flow charts are valid for both, installation in the supply or the
return pipe, provided the direction of flow conforms to the arrow
on the valve body.
In cooling systems using mixtures of water and glycol, the
correction factors related to the indicated chart values have to be
taken into consideration.
Advantages:
– the location of the functional components in one plane allows
a simple assembly and easy operation
– only one valve for 5 functions:
presetting
measuring
isolating
filling
draining
– the supply and the return pipe can be marked by use of the
colour rings supplied with each valve
both ports male thread
for weldable steel tailpipes
DN 10 up to DN 50
or:
... for solder tailpipes 15 mm Ø up to 54 mm Ø
– low pressure loss (oblique pattern)
or:
... for threaded tailpipes DN 10 up to DN 50
– infinitely adjustable presetting, exact measurement of pressure
loss and flow via the pressure test points
or:
…for female threaded tailpipes DN 15 up to DN 32
– threads according to EN 10226 (BS 21), suitable for Oventrop
compression fittings (1027151-58) for copper pipes up to a
max. diameter of 22 mm and Oventrop composition pipe
“Copipe”
– fill and drain ball valve with internal stop and pressure test point
with O-ring seal between valve body and test point (no
additional seals required)
– patented measuring channel led around the stem assembly to
the test points ensures the best possible accuracy between the
differential pressure measured at the pressure test points and
the actual differential pressure of the valve (see chart indicating
flow rate tolerances)

installed against the flow, an increase in the flow rate of 1-3%,
related to the chart value, must be considered.

Oventrop double regulating and commissioning valves serve to
achieve the hydronic balance between the various circuits of a
system. It is to be observed that the direction of flow conforms to

Measuring and regulation
Oventrop measuring system“OV-DMC 2”
(with memory and microprocessor)
featuring numerous functions and a wide range of applications:
– Flow rate indication (indication m3/h, l/s, l/min. und gal/min.)
– Differential pressure measurement (indication in mbar, kPa, PSI,
mm WG, m WG)
– Temperature measurement (indication in °C or °F)
– Presetting: Arriving at the presetting value based on the
measured differential pressure, the given flow rate
and the valve size.
The characteristic lines of all Oventrop regulating valves are
memorised in the flow-meter.
With the use of a respective kv value, it is possible to carry out
measurements on valves of other manufacturers.
(For practical use of the “OV-DMC 2”, special operating
instructions are available.)
Oventrop measuring system “OV-DMPC”
consisting of differential pressure transmitter “DMPC-sensor” with
USB interface and software including accessories. The measuring
system is connected to a commercial computer (not included).
