The GEMÜ N086 and N186 pressure retaining valves are used to provide a constant back pressure in process plant. They can also be used as pressure relief valves to reduce pressure peaks in the bypass. Due to their minimal deadleg design, types N086 and N186 are particularly well suited to ultra pure water applications. The product range has been expanded to include the pressure retaining valve GEMÜ N786.

Plant and piping systems are protected against gauge pressure and pressure peaks using pressure relief valves from the GEMÜ N085 and N185 series. A third pipe spigot facilitates installation in the main pipe through which any overpressure is relieved. Due to the cavity filled and flow-efficient design of the valve body, there is only a minimal pressure loss in the throughput.

GEMÜ pressure reducers are used to reduce the pressure to a specified value, which can be easily set using a set screw. The inlet pressure is reduced to the required outlet pressure utilizing the pressure differential.
