Pressure Relief Valves

Singer Valve manufacture a vast range of Pressure Relief Valves, all with different functions for different application requirements. Pressure Relief Valves are often used in Clean Water Industries to control surges of pressure within pipelines, acting as protection for the system. The Pressure Relief Valves operate by the Singer 81-RP pilot sensing upstream pressure through a connection to the valve inlet.

The valve and pilot remain closed until the inlet pressure exceeds the pilot setting. The valve opens rapidly to relieve damaging overpressure and closes smoothly at an adjustable speed when the pressure returns below the set-point.

MGA Controls Ltd are experts in the specification and supply of Pressure Relief Valves for a wide range of industries and applications.
