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.

Pressure Relief Valve suits economizer applications.

Certified under requirements of ASME Code Section I, pilot-operated Series 1500 is designed specifically for overpressure protection of economizers in fossil-fired power plants. All-plastic, soft seat valve operates as non-flowing modulating pilot, opens in proportion to relief demand, and is suitable for hot water, flashing water, and steam service. With no elastomer seats or seals, unit handles...

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...
