The pressure switch valve is a three way block and bleed valve that is operated by pressure acting on a piston
opposingan adjustable spring force. It functions as either a normally closed or normally open valve, depending on through which of the two ports the instrument pressure is supplied. These ports are marked as 'HIIlN' or 'LO IN' on the switch body. The output port, marked 'OUT' on the switch body, is the same for either mode of operation. Pressure applied to the sense port will cause the valve to operate.
