Silent Check Valve


NSCV - Non Slam Check Valve

NSCV- Non Slam Check Valve is used as  protection against reverse flow when  power failure in areas where noise pollution  or water hammering is a critical issue. It can  provide not only quiet performance but also low  head loss.

Features: ·High strength ductile iron 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 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 under protection while valve  in operation. ·Disc will positively close before  reverse flow, and maximize the  closing speed up to 0.2 Sec. · Installation can be vertical/horizontal/ inclined. For size DN800 and up  preferred vertical installation.  ·Comply with EN 558-1, ISO 5752  and EN 1092-2, ISO 7005-2 flange  dimension.

Service Fields: Mainly used for clean water, precleaned  sewage water, Fire-fighting, Irrigation,  Cooling and HVAC System.

Technical Data: Size Range: DN50-1800mm Pressure Ratings: 1.0Mpa; 1.6Mpa; 2.5Mpa. Working Temperature: -100 C-800 C Flow Media: Clean Water End Connections: PN10, PN16, PN25.
