Overview
List of Accessories
Typical Applications

RS300 lightweight pressure relief valve/pressure holding/back pressure valve is a hydraulic control valve controlled by a pressure regulator, can maintain pressure in upstream pipelines, can be used in pressure relief, pressure holding and back pressure impact situations. During operation, the valve senses inlet pressure of the valve by the pressure regulator to control valve opening or closing. When inlet pressure exceeds the set value, the valve will open quickly to maintain pressure in the pipelines. After pressure release, the valve will close slowly to prevent impact.

Typical Applications

As A Pressure Relief Valve

To prevent high-pressure impact generated during pump shutdown, the quick opening and slow closing the pressure relief valve can be used to release excess high pressure to protect the system.

As A Pressure Holding Valve

When the valve is installed between the high-pressure supply at upstream and large-flow demand at downstream, a pressure holding valve is used to maintain high pressure at upstream, so as to prevent pressure in the main pipe from dropping continuously due to excessive flow demand at downstream to maintain pressure in the main pipe.
