Althon WaStop Check Valve

The WaStop is made up of a stainless steel 304 tube, incorporating a cone-shaped chloroprene membrane. The membrane allows flow to pass in the desired direction, however when back-flow occurs, this fills the membrane, sealing the pipe.

The design of the Althon WaStop check valve means that it does not block easily, and that the leakage is minimal when debris becomes trapped.  As the WaStop does not rely on gravity to close the membrane, it does not need to be fitted against a vertical headwall. This means that it can be installed in any plane, or inline between two pipes.

The WaStop can be fitted in a number of ways, such as wall mounted at the inlet or outlet using the “manhole installation” wall mounting method, flange mounted or mounted using a flexible coupling.

The WaStop is available in a number of standard sizes, suitable for up to 8m of water pressure, however special sizes and pressures are available on request. For some applications, Stainless Steel 316 pipe can be used, for example in heavily saline environments, or for smaller applications, HDPE tube can be used to support the membrane, which can be coupled in the usual ways
