Fisher ? Fisher 75A water pressure regulator：Threaded NPT bronze body with Nitrile (NBR) disk. Inlet pressures to 200 psig. Reduced pressures from 20 to 80 psig with minimum 5 psig differential pressure.

The type 75A regulator is designed to reduce the pressure of domestic or industrial water, thus preventing damage under high pressure impact of piping facilities and instruments. 75A valve is self-contained design, and it can work without external control pipeline. The downstream pressure is directly taken on the valve film. With the increase of downstream pressure, the pressure of the valve film is spring pressure, which makes the valve disc rise and reduces the flow through the pressure regulating valve.
