Product Description
Nozzle Check Valve


Low weight discs,short stroke lengths and spring assistance combine to ensure that the Nozzle Check Valve respinds quickest to changed in flow direction. This exceptionally fast respinse ensures reverse velocity cannot build up to a level that can damage pumps,pipes or related equipment.As pressure surges can occur when a valve is closed against a moving body of fluid, the quick closure results in a considerably ower pressure peak than any other type of check valve.
