2011 Oventrop 1 Bronze double regulating and commissioning valves PN 16/PN 25 “Hydrocontrol VTR/VPR” Function: Oventrop double regulating and commissioning valves are instal- led 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 position. The required values of presetting 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 Oven- trop 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. The flow charts are valid for both, installation in the supply or the return pipe, provided the direction of flow conforms to the arrow embossed on the valve body. In cooling systems using mixtures of water and glycol, the cor- rection factors related to the indicated chart values have to be taken into consideration. Advantages: – the location of the functioning components on one level 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 – low pressure loss (oblique pattern) – infinitely adjustable presetting, exact measurement of pressure loss and flow via the pressure test points – threads according to EN 10226 (BS 21), suitable for Oventrop compression fittings (102 71 51-58) 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 addi- tional 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) both ports female thread according to EN 10226 (BS 21) DN 10 to DN 65 both ports male thread for weldable steel tailpipes DN 10 up to DN 50 or: ... for solder tailpipes 15 mm up to 54 mm or: ... for threaded tailpipes DN 10 up to DN 50 or: …for female threaded tailpipes DN 15 up to DN 32 Technical information Designation: new old “Hydrocontrol VTR” “Hydrocontrol R” Bronze double regulating and commissioning valve PN 16/PN 25 “Hydrocontrol VTR”

Oventrop double regulating and commissioning valves are instal-led in the pipework of hot water central heating and coolingsystems and serve to achieve a hydronic balance between thevarious circuits of the system.
The balance is achieved by a presetting with memory position.
The required values of presetting can be obtained from the flowcharts. All intermediate values are infinitely adjustable.
The selected presetting can be read off two scales (basic scaleand fine adjustment scale, see illustration presetting). The Oven-trop double regulating and commissioning valves have 2 threadedports for fill and drain ball valves or pressure test points for themeasurement of differential pressure.
The double regulating and commissioning valves may be installedin either the supply or the return pipe.
When installing the valve it must be ensured that the direction offlow conforms to the direction of the arrow on the valve body andthat the valve is installed with a minimum of L = 3 x Ø of straightpipe at the valve inlet and of L = 2 x Ø of straight pipe at the valveoutlet.
The flow charts are valid for both, installation in the supply or thereturn pipe, provided the direction of flow conforms to the arrowembossed on the valve body.
In cooling systems using mixtures of water and glycol, the cor-rection factors related to the indicated chart values have to betaken into consideration.
Advantages:
– the location of the functioning components on one level allowsa simple assembly and easy operation
– only one valve for 5 functions:presettingmeasuringisolatingfillingdraining
– the supply and the return pipe can be marked by use of thecolour rings supplied with each valve
– low pressure loss (oblique pattern)
– infinitely adjustable presetting, exact measurement of pressureloss and flow via the pressure test points
– threads according to EN 10226 (BS 21), suitable for Oventropcompression fittings (102 71 51-58) for copper pipes up to amax. diameter of 22 mm and Oventrop composition pipe“Copipe”
– fill and drain ball valve with internal stop and pressure test pointwith O-ring seal between valve body and test point (no addi-tional seals required)
– patented measuring channel led around the stem assembly tothe test points ensures the best possible accuracy between thedifferential pressure measured at the pressure test points andthe actual differential pressure of the valve (see chart indicatingflow rate tolerances)

Presetting
Presetting:
1. The value of presetting of the valve is set by turning the hand-wheel.
a. The display of the basic setting is shown by the longitudinalscale together with the sliding indicator.
Each turn of the handwheel is represented by a line on the lon-gitudinal scale.
b. The display of the fine setting is shown by the peripheral scaleon the handwheel together with the marking. The subdivisionsof the peripheral scale correspond to 1/10th of a turn of thehandwheel.
2. Limitation of the set value of presetting by turning the inneradjustment stem clockwise until it seats. This can be done byusing the long end of a 3 mm Allen key.
Marking of the flow and return pipe:Clip one of the colour rings (red = supply, blue = return) suppliedwith each valve onto the handwheel.

Oventrop double regulating and commissioning valves serve toachieve the hydronic balance between the various circuits of a sy-stem. It is therefore to be observed that the direction of flow con-
forms to the arrow on the valve body. The flow tolerance is � 5%.If installed against the flow, an increase in the flow rate of 1-3%,related to the chart value, must be considered.
