Vacuum/pressure relief valve

The vacuum/pressure relief valve FPZ is designed to limit in case of low pressures/depressions with minimum hysteresis (the difference between the value of start of the intervetion and the adjusted value).

Thanks to a compact design, the vacuum/pressure relief valves FPZ are easy to install and calibrate, and are made of aluminum alloy.

The vacuum/pressure relief valves FPZ guarantee maximum efficiency and are able to work in a wide range of flow rates and ensure the possibility of in-line mounting in case it is necessary to convey the secondary stream.
