The Herz 7DQ7XP is a high-quality membrane pressure reducing valve, specifically designed for use in drinking water installations. This genuine Herz component, also known by its official article number 1268211, features a 1 1/2 inch (DN40) connection and is engineered to maintain a stable and reduced outlet pressure, protecting downstream components from excessive inlet pressure fluctuations. Constructed with a durable brass body, stainless steel filter screen, and an EPDM diaphragm, it ensures reliability and compliance with EN 806-2 standards for drinking water applications. The outlet pressure is adjustable from 1.5 to 6 bar, with a factory setting of 4 bar, and it can handle a maximum inlet pressure of 16 bar and an operating temperature of up to 30°C.
