Check Valves

Use these high-pressure poppet check valves in the most demanding applications, such as medical devices, products optimized for cryogenic applications, and severe service designs.

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.

Compact and featuring a one-piece body, this adjustable check valve is factory-tested for leakage, crack, and reseal performance. Ideally suited for oxygen service applications, this valve also features a fully retained O-Ring seal.

With dependable leak and bubble-tight options, this valve provides free flow in one direction and shut-off in the opposite direction. Encapsulated ball virtually eliminates flutter yet provides a positive check.

Particularly suitable for applications in instrumentation and control panels to open and close circuits or isolate gauges, this quick opening valve offers a unique design for full-closed to full-open operation with a 60° turn of the knob.

Unique, externally adjustable, and wear compensating, this screwed bonnet-type needle valve offers a long and trouble-free service life in most liquid or gas applications.
