CVII Resilient Flap Check Valve

Category:

The VSI Waterworks’ CVII features a uniquely simple design utilizing no moving parts. The flapper does not rely on a hing pin to swing, instead it simply flexes open. The short travel of the flapper ensures a quick closure before flow can reverse. The fully resilient encapsulated disc inherently seals itself and allows no slam. Available with backflow actuator. Designed per AWWA C508 and available in flanged as well as mechanical joint for direct bury applications.
