Pressure Reducing Valve D04FM, residential use, 1/2" thread, 1.9 Kvs. These types of pressure reducing valves protect domestic water installations from excessive supply network pressure. They can also be used for industrial and commercial applications within their specification range. By installing a pressure reducer, overpressure damage is avoided and water consumption is reduced. The set pressure remains constant even with wide fluctuations in the inlet pressure. Reducing the operating pressure and maintaining it at a constant level minimises noise in the installation. Certifications: DVGW according to DIN EN1567 (in process) WRAS according to BS EN1567 (in process). Compact construction. The adjustment spring is not in contact with the drinking water. The outlet pressure is adjusted using the green control knob. Balanced inlet pressure - inlet pressure variations do not affect the outlet pressure. Complies with KTW/W270, WRAS, and ACS directives for drinking water. Medium: water. Max. working temp: 40C (70C for max. pressure 10bar). Body material: brass, dezincification resistant.
