The Tideflex Checkmate Inline valve prevents unwanted backflow that can cause surcharging and flooding. The Tideflex Checkmate is an inline check valve designed to be installed at the upstream or downstream side of a diversion chamber. The entire valve is constructed of rubber, making it rust-free and resistant to grease and oils typically found in wastewater. Additionally, with seven elastomers to select from, the Tideflex Checkmate can be manufactured to resist chemicals found in industrial wastewater applications. A major advantage of the Tideflex Checkmate Inline valve is its extremely low headloss. This is particularly beneficial in low-lying areas. Tideflex Checkmate valves drain with very low head pressure and are sensitive enough to open with as little as 1" of water.

Interceptor and Manhole Installations

The Tideflex Checkate Inline valves are used for interceptor and manhole installations because they are ideal for preventing water from back flowing into a sewage treatment plant. The Tideflex Checkmate valve’s innovative inline design allows it to be installed without modifications to structures such as interceptors, manholes and vaults.

Storm water Runoff

The Tideflex Checkmate Inline valve is the valve of choice for both municipalities and commercial property owners in storm water and general drainage applications. Because the Tideflex Checkmate valve utilises dissimilar elastomers and fabric in the hinge area, there are no mechanical parts to warp or corrode. It is maintenance-free.
