Quick Close Non Slam Check Valve With Anti Water Hammer Function

Description:

Non Slam Check Valve is usually used as a protection device against reversed 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.

Size:DN50-1000MM

Pressure Rating:PN10,PN16,PN25

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.
·Comply with EN 558-1, ISO 5752 and EN 1092-2, ISO 7005-2 flange dimension.
