NSCV – DN 400-1200 (Non Slam Check Valve)
Spec Sheet: NSCV – DN 400-1200 (Non Slam Check Valve)
NSCV- Non Slam Check Valve is used as protection against the 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.
Description
Non Slam Check Valve
Features:
·High strength ductile iron body used for durability and less weight.
·Advanced dynamic design of the single body with diffuser provides streamlined flow and assures lower head loss.
·One of the lowest headloss check valves, big save in pumping power cost, valve disc with shorter stroker and spring reverse faster than most the check valve.
·Coated with powder epoxy both inside & outside for corrosion resistance.
·Bronze bushing reduces wearing problems during operation.
·Hydrodynamic design with spring ensures non-slamming and water hammerless.
·Stainless steel spring is hidden in the diffuser under protection while the valve is 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.
