Rubber Duckbill Check Valve

Our Rubber Duckbill Check Valve is a flexible non-return valve designed to control the direction of flow in water, drainage, and general pipework applications.

The flexible rubber body provides a check-valve function without relying on a conventional mechanical valve mechanism. The valve is designed to allow flow in the intended direction while helping restrict reverse flow.

Constructed from rubber and stainless-steel components, the valve is supplied with a clamp-style connection and is available in a range of sizes from DN32 to DN300. Available sealing material options include EPDM, FKM, silicone, and rubber to suit different project requirements.
