Valves, controllers + systems Double regulating and commissioning valves Hydrocontrol F cast iron, PN The Oventrop Quality Management System is certified to DIN-EN-ISO 9001 Technical information Application: Oventrop double regulating and commissioning valves "Hydrocontrol F are installed in the pipework of hot water central heating systems 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 that 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 due to the moveable display, exact measurement of pressure loss and flow by using the 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 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 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 valve in the supply or the return pipe provided 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.

The value of presetting of the valve is adjusted by turning the handwheel. a. The display of the basic setting is shown by the longitudinal scale together with the sliding indictor. 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/th of a turn of the handwheel. 2. The set value of presetting can be limited by turning the inner adjustment stem clockwise until it seats. This can be done by using the long end of a 3 mm Allen key. Visibility/readability of the setting scales: Depending on the installation position of the double regulating and commissioning valve, an improvement of the visibility/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 is clearly visible. Finally refit the handwheel to the valve stem, tighten the screw and replace the cover plug. Protecting the presetting: The sealing wire, item no. 8 90 91, which is to be ordered separately, may be fitted through the hole in the handwheel and a lead seal may be fitted. Locking the handwheel: The handwheel can be locked in any position (1/th of a turn). To do so, the existing cover plug is replaced by the locking set, item no. 6 01 80, which is to be ordered separately. In addition, the locked handwheel can be secured by use of the sealing wire.

Measurement and regulation Flow-meter "OV-DMC 2 with memory and microprocessor featuring numerous functions and a wide range of applications: flow rate indication (in l/s, m3/h and gal/min) differential pressure measurement (indication in mbar, Pa or kpa) temperature measurement (indication C or F) presetting Arriving at the value of presetting based on the measured differential pressure, the given flow rate and the valve size. The characteristic lines of all Oventrop double regulating and commissioning valves 3/8 are memorised in the "OVDMC 2. With the use of a respective kv value, it is possible to carry out all measurements on valves of other manufacturers. For practical use of the "OV-DMC 2, special operating instructions are available. Flow-meter OV-DMC 2, item no. 6 91 77 with Hydrocontrol F/FR/FS Electronic differential pressure gauge Pocket size differential pressure gauge for practical use on site for checking p in conjunction with Oventrop double regulating and commissioning valves. To measure static pressure, connection of one only sensor is necessary. Digital indication in kpa units. Electronic differential pressure gauge, item no. 6 91 2 with Hydrocontrol F
