Check Valves

Swing Check Valve -- Outside Lever & Weight WCB

Swing check valves in WCB carbon steel with outside lever and adjustable cast iron weight for controlled, non-slam closure in water distribution, cooling water, and fire water systems. The external lever and weight allow operators to adjust closing speed to match pump stop characteristics and minimise water hammer. Full port design ensures low pressure drop, while the robust hinge and renewable seat ring extend service life in continuous duty.
