Silent check valves, also known as non-slam check valves and spring-assisted check valves reduce or eliminate water hammer and its effects.
· 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.
