Pressure retaining or pressure relief valves are used where a constant back pressure is required to operate process plants. When used in bypass, they can also be used as overflow valves.
Overflow valves reliably protect plants and piping systems against pressure peaks. The integrated overflow outlet allows installation directly in the main line.
Pressure reducing valves reduce the system pressure to a specified working pressure by utilizing the differential pressure and thus protect downstream equipment. Furthermore, they absorb pressure fluctuations to the greatest possible extent, thus ensuring equalized pressure at downstream consumers.
