It is actuated with a foot pedal with mechanical safety latch. The safety latch opens at actuation and returns back automatically to the normal position after release of the pedal. As long the pedal is not actuated, the flow medium will be led through the bypass line and the high-pressure unit becomes pressureless. The foot valve is available for various hose connectors on high-pressure water inlet (P) and high-pressure water outlet (A). All materials coming in contact with the pumped media are of corrosion- and acid-resistant CrNi-steel.
