Shand and Jurs 94640 Pilot Operated Relief Valve

Hillside, IL — The Shand Jurs Pilot Operated Relief Valve is designed to meet very specific pressure needs. The high accuracy of the valve allows the pressure to be set between 3 of water column pressure and 15 psig using sensitive springs for discrete ranges. The valve operates as follows. As the internal pressure reaches the valves set point, the upward force on the sensing diaphragm...
