Silent Check Valve Product Descriptions

Silent check valve is also called globe type check valve or nozzle check valve, which can close without water hammer. Silent check valves are designed to react to the high deceleration rates by closing very quickly, prior to the reverse velocity reaching damaging levels. Globe type check valve is used widely in where forward flow can turn into reverse flow quickly. Flowspec Luokai design and manufacture the silent check valve according to BS5153 and MSS SP-71 with sizes of 2″~12″ (DN50~300mm). Just feel free to contact us now to get best prices. 30 years of experience.
