Valves

Compact and highly accurate, this vent relief valve is factory preset to desired crack pressure and/or flow specifications. With an internal adjustment, this valve provides tamper-proof safety against inadvertent pressure changes and features an encapsulated O-ring seal to prevent extrusion at higher differential pressures.

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.

Suitable for both gas and liquid applications, this poppet check valve features a fully retained O-ring seal design that permits full-rated pressure in the checked direction. With a metal-to-metal positive stop, this valve provides a trouble-free service life in the most demanding applications.
