Description

These valves are operated by the pressure applied to the sense port acting on a piston opposing an adjustable spring force.
3 way valve is a block and bleed valve.It functions as either a normally closed or normally open valve, depending on through which port the instrument pressure is supplied. These ports are marked as “HI In” or “LO IN” on the switch body. The output port, marked “OUT” on the switch body, is the same for either mode of operation.
2 way valve is functions as a normally closed or normally open valve, depending on customer requirement.See Valve Ordering Code.
