Braukmann Priority valve, VV300

Braukmann Priority valve, VV300

Product Description

VV300 priority valves are a combination between pressureregulating and pressure limiting valves. They are used toensure priority drinking water supply to important systems.Ancillary systems are then supplied only when there is sufficient surplus drinking water available. In addition downstream installations are protected against excess supply pressures. The compact construction makes them particularly suitable for applications where space is limited, for example in ducts. The application of priority valves prevents pressure damage. The set pressure remains constant even when the inlet pressure fluctuates greatly.
