This robust and reliable foot valve to close / open a high-pressure line (basic position "closed") is operated by a foot lever with mechanical safety latch. The safety latch releases the movement of the actuating lever and, upon release of the lever, automatically returns to the safe position. The proximity switch detects the foot lever position and triggers the control signal. With this foot valve, additional valve units as well as complex control units can be remote-controlled, thus enhancing work safety and work comfort. The foot valve is available with various hose connections for pressurized water inlet (P) and pressurized water outlet (A). All parts that come into contact with the medium consist of stainless and acid-resistant CrNi steels.
