gas relief valve

SPM® offers nitrogen relief valves in two styles, a reseatable backpressure valve and a dump-style full bore unloading valve.

Weir SPM® nitrogen actuated relief valves come in two versions: a backpressure relief valve and a full bore unloading valve. The EXL backpressure relief valve is the next generation in SPM’s back pressure relief valve offering. The valve features a threaded body, more compact envelope and changes to internal features that improve serviceability. This valve is able to reseat, making it possible to continue operation after the valve has vented.
