The Oventrop Quality Management System is certified to DIN-EN-ISO 9001 Application: Oventrop double regulating and commissioning valves Hydrocontrol G 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 double regulating and commissioning valves may be installed in either the supply or the return pipe. When installing the valves, it is to be observed that the direction of flow conforms with the arrow on the valve body and the valve is installed with a minimum of 3 D (3 x nominal pipe diameter) of straight pipe at the valve inlet and of 2 D (2 x nominal pipe diameter) of straight pipe at the valve outlet. Advantages: the location of the functioning components on one side allows a simple assembly and easy operation only one valve for functions: presetting measuring isolating filling draining low pressure loss (oblique pattern) infinitely adjustable presetting which can be read off in any position of the valve, exact measurement of pressure loss and flow by use of pressure test points fill and drain ball valve with internal stop and pressure test point with O-ring seal between valve body and test point (no additional seal 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 point and the actual differential pressure of the valve Function: The balance is achieved by a presetting with memory position. The calculated flow rate or pressure loss for each individual pipe can be preset centrally and be regulated precisely. 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 setting longitudinal scale and fine setting peripheral scale, see illustration presetting). The presetting is reproducible by opening the valve until stop. The flow charts are valid for the installation of the double regulating and commissioning valves in the supply or the return pipe, provided that the direction of flow conforms with the arrow on the valve body. The Oventrop double regulating and commissioning valves have two threaded ports which are equipped with the pressure test points for measuring the differential pressure.

Pressure test point and fill and drain ball valve interchangeable. 2 1/2-6 : 1. The value of presetting of the valve is adjusted by turningthe handwheel. a. The display of the basic setting is shown by the longitudinal scale together with the sliding indicator. Each turn of the handwheel is represented by a line on the longitudinal scale. b. The display of the fine setting is shown by the peripheral scale on the handwheel together with the marking. The subdivisions of the peripheral scale correspond to 1/10th of a turn of the handwheel. 2. Remove cover plug by introducing a screwdriver in the slot and gently prising it off. 3. Undo screw by use of a 8 mm Allen key. 4. With the valve at the required value of presetting, turn the inner adjustment stem clockwise until it seats. This can be done by using the long end of a 4 mm Allen key.. Replace and tighten screw by use of a 8 mm Allen key. 6. Refit cover plug. Visibility/readability of the setting scales: Depending on the installation position of the double regulating and commissioning valve, an improvement of the visibil ity/readability of the setting scales is obtained by twisting the scales. With the valve fully closed and the two setting scales on 0, remove cover plug, undo screw and with a light tug pull the handwheel from the valve stem. Next, without altering the presetting (still indicating 0 ), adjust the position of the handwheel so that the indicator window of the longitudinal scale is clearly visible. Finally refit the handwheel to the valve stem, tighten the screw and replace the cover plug.

Fit the enclosed clip in the cut-out in the handwheel below the holes between the guides, making sure it locates into the sliding indicator (see sketch). The clip can now be sealed as illustrated. It is essential that the sealing wire is fitted tightly. Clip Lead seal

Measurement and regulation 2 1/2 Oventrop flow-meter OV-DMC 2 with memory and microprocessor featuring numerous functions and a wide range of applications: - flow rate indication (l/s, m3/h and gal/min.) - differential pressure measuring (indication in mbar, Pa or kpa) - temperature measuring (indication in C or F) - presetting. Arriving at the value of presetting based on the measured differential pressure, the given flowrate and the valve size.
