The Check-Flex valves are an inline check valve that seals directly to the pipe, meaning no work is needed to the existing wall opening or benching. 

The valves one piece design allows the valve to flex without the point stress of older three piece assembled design. The valve combines a Sealing Gasket, Moving Flap and Container into a single integrated product. There is no hinge mechanism to be maintained.

Rated for severe service including unscreened highway run off and even steam detergent wash down areas in food plants. Fibre reinforcement prevents tearing from glass shards, grit and debris. Neoprene will flex without fatigue in the same way as a tyre flexes each rotation.
