Non Slam Check Valve EPOXY Coated Ductile iron with antI water hammer function
Description
NSCV- Non Slam Check Valve is used as protection against reverse flow when power failure in areas where noise pollution or water hammering happens. It can provide not only quiet performance but also low head loss.
Features:
·High strength ductile iron body used for long service life and less weight.
·Advanced dynamic design of single body with diffuser provides streamline flow and assures lower head loss.
·One of the lowest head loss check valve, big save in pumping power cost, valve disc with shorter stroker and spring reverse faster than most of check valve.
·Coated with powder epoxy both inside & outside for corrosion resistance.
·Bronze bushing reduce wearing problem during operation.
·Hydrodynamic design with spring ensures non slamming and water hammerless.
·Stainless steel spring hidden in the diffuser will not easily blocked by impurities
·Disc will positively close before reverse flow, and maximize the closing speed up to 0.2 Sec.
· Installation can be vertical/horizontal/inclined.
·Comply with EN 558-1, ISO 5752 and EN 1092-2, ISO 7005-2 flange dimension.
