Anti Water Hammer No-return Check Valve  Quick Close Ductile iron Body

 

 

 

Description

 

NSCV- Non Slam Check Valve is used as a protection against reverse flow when power failure or off in areas where noise pollution or water hammering is a critical issue. It can provide both quiet performance and low head loss.

 

Features:

 

·High strength ductile iron valve body used for durability 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 epoxy powder both inside & outside for corrosion resistance.
·Bronze bushing reduce wearing problem on operation.
·Hydrodynamic design with spring ensures non slamming and water hammerless.
·Stainless steel spring hidden in the diffuser under protection while valve in operation.
·Disc will positively close before reverse flow, and maximize the closing speed up to 0.2 Sec.
· Can be vertical/horizontal/inclined installation.
·Meet EN 558-1, ISO 5752 and EN 1092-2, ISO 7005-2 flange dimension.
