Pressure reducing valve D04FM, residential use, 1/2" thread, 1.9 Kvs. Pressure reducing valves of this type protect domestic water installations from excessive supply network pressure. They can also be used for industrial and commercial applications within their specification. By installing a pressure reducer, damage from overpressure is avoided and water consumption is reduced. The established pressure remains constant even when there is a wide fluctuation in the inlet pressure. The reduction in operating pressure and maintenance at a constant level minimizes 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 drinking water. The outlet pressure is adjusted using the green control. Balanced inlet pressure - variations in inlet pressure do not affect 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, resistant to zinc loss. Spring material: synthetic material. Internal/External connection: external thread. Static pressure: PN16. Adjustable pressure range: 1.5...6bar. Flow Kvs: 1.9. Standard model.
