Structure
Application
▪ This check valve is a new type of waterproof hammer energy-saving product with vertical or inclined valve seat, double offset disc, all metal sealing pair and wear-resistant rubber sealing pair, overflow element with channel fluid and oil pressure slow closing device, which can close the valve in fast / slow stages.
▪ The valve can save energy obviously in operation. When the pump is normal or the pump is stopped in case of sudden power failure, it can effectively prevent the backflow of water body and the occurrence of destructive water hammer.
▪ It’s widely used in petrochemical, power metallurgy, urban water supply and drainage and other pipeline systems.
