FEATURES

• Silent 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 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.
