Rubber Flapper Check Valve

The GA Rubber Flapper Check Valve’s simple, one moving part design provides long term maintenance-free operation, low headloss and excellent solids handling characteristics.  It’s smooth, unrestricted flow path makes it an ideal choice for handling sewage, sludge and other solids bearing fluids but it is equally well suited for use on clean fluids.  Additional features like visual and/or electrical position indication, back flow device and spring assisted closure (Slaminator™) allow the valve to be customized to suit the needs of the application.
