The Shutoff and Inline Relief Valve is milled from aircraft-grade aluminum and hard coat anodized to be sturdy and durable. Designed to relieve over-pressurization and allow a lift bag to remain inflated under a load. This valve will relieve excess pressure from an inflated air lifting bag caused by load shifts or temperature changes. Its safety coupling has a threaded safety lock system that vents system air unless secured to the input nipple.
