ACMO tilting disc check valves are installed in pumping applications to prevent backflow in the system. All interior parts are stainless steel or coated with drinking water approved epoxy. Measures are available to mitigate pressure surges like a lever and a weight fitted to the shaft end to help close the valve before the flow changes direction.
