Technische Spezifikationen der Wasserdruckregler

DN of the pressure regulator — the nominal diameter of the opening in the connecting nozzles. The value of DN is used to standardize the sizes of pipeline fittings. The actual diameter of the opening may slightly differ from the nominal diameter in either direction.

PN of the pressure regulator — the nominal pressure is the maximum excess pressure of the working medium at a temperature of 20°C, which ensures long and safe operation.

Kvs of the pressure regulator — the coefficient of flow capacity corresponds to the water flow rate, m³/h at a temperature of 20°C, at which the pressure drop on the valve of the regulator will be 1 bar. The value of the flow capacity coefficient is used in hydraulic calculations to determine the head loss.

Adjustment range — the range of pressures maintained by the regulator depends on the spring elasticity (setting force).
