Non Slam Check Valve DN50 to DN1200

DN50 to DN1200 PN16/25 -10°C to 70°C

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.

  • 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 stoke and spring reverse faster than most other check valve.
  • Coated with powder epoxy both inside and out 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 is in operation
  • Disc will positively close before 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.
