IPS Pressure Reducing Valves Irrigation Pumping Station

Description

The design of the Pressure Reducing Valves has been made for reducing the incoming water or steam pressure for a safer constant predetermined downstream level. Depending on the type of valve, the downstream pressure has been established by a pressure adjustment setting on the valve or by an external sensor. These valves are used in commercial, residential, industrial, and institutional applications.

Main components of a pressure reducing valve:

The pressure reducing valve has a lot of elements for assisting with optimal function. These are the Valve body, Pilot regulator, and Large control filter.

Functions of a Pressure Reducing Valve

These valves have been designed to withstand even the toughest environments and are operated hydraulically. They are actuated by diaphragm control valves which reduces the higher upstream pressure for lowering the constant downstream pressure without any regards for the fluctuating demand or the varying upstream force. The valve maintains a steady state of pressure downstream, heedless of flow.
