HydroControl D Differential pressure regulator with internal thread PN 25
DN 50, Rp 2, nominal value 250-700 mbar

For automatic hydronic balancing of distribution pipes in central heating and cooling systems with closed circuits. The differential pressure control ensures hydronic balancing even at partial load and prevents high differential pressures in the controlled system section, e.g. at the radiator valve. When using a HydroControl V as partner valve, the water quantity in the riser can also be measured with the help of the OV-DMC 3 measuring system with the impulse tube connected.

Y-pattern valve with secured, at any time controllable, infinitely adjustable presetting of the desired nominal differential pressure value. All functions accessible from the top.
