Y-type quick closing valves is mainly mounted in the outlet pipeline of water pump, with funtions of non-return and quick close No backflow, small head loss, prevention of water hammer, all there effectively improve the safety of water transporting system. Mwanwhile, this valve is equipped with flow regulating device to freely control the flow of valve. it can be manually closed when necessary.
Water hammer & noise elimination: it's start and stop is interlocked with main disc, can automatically effect qucik close without the influence of flow in water hammer to minimum when pump stops.
Compared with similiar imported products ,it's resistance loss lowers over 50%.
