NSF Certificated Ductile iron Anti Water Hamme Low Head Loss Non Slam Check Valve EPOXY Coated
Description
NSCV- Non Slam Check Valve can provide not only quiet performance but also low head loss. It's generally used as protection against reverse flow when power failure in areas where noise pollution or water hammering is a critical issue. NSCV is used against water reverse flow suddenly and protects pump and other devices from water hammer harmness. It is mainly used for clean water.
Features:
1. Very short face to face distance, closing is so quick up to max 0.2sec speed, switch procedure is only about 20% of valve bore diameter, hydrodynamic design with spring ensure non slamming and to minimize the water hammer
2.Diffuser design-lowest head loss and streamline flow
3.Bronze bushing can reduce the stem wearing while working and last the service term
4.Can return investment within1 year by using right NSCV
