Design
The Crosby Style JCE Safety Relief Valve incorporates a freely pivoting disc, which ensures correct alignment with the nozzle. The combination of top guiding, unobstructed seat bore and full lift capability ensures the highest possible discharge rate thus maximum plant protection. Body material is available in cast steel and stainless steel.
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%. Valve size ranges from DN 25 to DN 100 (1” to 4”).
