For automatic hydraulic balancing of distribution lines in central heating and cooling systems with closed circuits. The differential pressure regulator guarantees hydraulic balancing also in the partial load range and prevents high differential pressures in the controlled area of the system, e.g. at the radiator valve. Measuring the amount of water in the riser when using the HydroControl V valve in cooperation with the OV-DMC 3 measuring system is also possible with a pulse tube connected.In a slanted design with secured, continuously controllable, stepless presetting of the required differential pressure value. All functional elements on the knob side. HydroControl D balancing valves are supplied with impulse tube and HydroPort auxiliary valve installed.The regulator body and parts in contact with the medium made of dezincification-resistant brass, stainless steel or EPDM.
