Independent spring design

A spring design of dual plate check valve(6” and larger) allows higher torque to be exerted against each plate with independent closing in response to the process stream.testing has proved this action provides about 20% improvement in valve life and 50% reduction in water hammer.Each of the dual plates has its own springs,which provide independent closing action
