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...

Sequence/Relief Valve features pressure range of 0-20 psi.
Relief Valves

Sequence/Relief Valve features pressure range of 0-20 psi.

Designed for precise control in pneumatic circuits, Model R-6100 can be used as relay valve to sequence specific signal operation, or as relief valve to limit pressure. Fixed or adjustable pressure settings are available. To adjust valve, user turns adjusting screw clockwise to reach zero adjustment, then turns adjusting screw counterclockwise to desired relieving or sequencing pressure.

Relief Valves

Right Angle Relief Valves range from 5-6,000 psig.

Series R6000 includes low-pressure models from 5-550 psig and high-pressure versions from 150-6,000 psig. Both feature raised seal lip that minimizes contact with seat, eliminating friction and preventing O-ring overstressing. Frictionless poppets ensure consistency of cracking and reseat pressures. High-pressure models are equipped with Delta stem seal, while low-pressure models have...
