Slurry Air Release Valve

Air/Vacuum Valve’s function is to automatically exhaust large volumes of air from the system when it is being filled and also to allow air to re-enter the pipe line when being emptied. The orifice size is generally the same size as the valve inlet and outlet.

Free Flow Valve

Free Flow Valve operates on the discharge side of the pump as the flow through the pipeline starts or stops, the ball automatically rises or falls, opening and closing the valve. This occurs without noticeable shock or hammer, regardless of the line pressure or the speed of closure.

flo stop high pressure mine dewatering check valve
Flo Stop Valve

Flo-Stop Valve has a reinforced stainless steel ball. The unique design of the valve allows free movement of the ball. The ball lifts out of the liquid without any interference. As the pump stops, the ball falls back and positively locates in the stainless steel seat due to its own weight and back pressure of the liquid. The higher the pressure the better the secondary Linatex seal will seal.
