Differential

The Ruelco SS series differential pressure switch is a three way block and bleed valve that is operated by pressure acting on a piston opposing an 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. Pressure applied to the sense port will cause the valve to operate.
