Upstream pressure relief regulator, high pressure

Code: R710HP

R710HP

The R710HP high pressure relief type valve has been designed to satisfy the industrial demand for a direct acting pressure regulator capable of accurately controlling liquids and gases (not steam).

It is robustly constructed with body rating up to ANSI 2500 and RTJ as optional.

The valve is of the piston operation type to attain the high set pressure.

Operation

When the upstream pressure rises beyond ‘set point’ the force acting on the piston increases, lifting it and compressing the control spring. This also raises the plug, opening the valve and allowing excess fluid to escape through the outlet port.
