Diverter valves for LNG vessel safety

Flow diverter valves provide overpressure protection of LNG storage vessels by their dual relief valve insertions for increased safety. They are commonly found and required in stationary LNG tanks, bulk vessels, manifold process systems and other LNG and cryogenic applications

Product description

Working in conjunction with two relief valves, the diverter valves retain continued performance without sacrificing safety when a valve undergoes maintenance and is disconnected.
