Designed with a free-floating O-ring for improved tolerance to particular contaminations, this high-flow, zero-leak, low-pressure check valve is suitable for fluid and gas applications. With metal-to-metal positive stops in both the open and checked position, this valve protects the O-ring and spring from over-stress fatigue.
