Crosby JCE pressure relief valves

The JCE Safety Relief Valve is available in both conventional and balanced bellows types, and features a special disc style for liquid application, ensuring trouble free performance.
The ‘conventional’ arrangement is suitable for applications where the built up pressure will not exceed 10%. The conventional valve can also be used in systems where the superimposed backpressure is at a constant level (up to 80%). The ‘balanced bellows’ arrangement is for applications where several safety relief valves discharge into a common discharge manifold, or in any circumstances where a variable back pressure can occur, up to a maximum of 40%.
