Swagelok® Check Valves

Swagelok check valves come in a broad range of adjustable and fixed cracking pressures to control back flow in general-service and high-purity applications. Excess flow valves will stop the release of excess flow downstream, enhancing system integrity and safety.

Check and Excess Flow Valves

Check Valves

Check valves are designed to allow fluids to flow in one direction only and are rated for use in medium- and high-pressure applications. Swagelok check valves come in a variety of designs, including spring and poppet, lift, and all-welded high-purity for use in a range of situations.

XS Series Excess Flow Valves

XS series valves have a slotted poppet which moves to the tripped position when excess flow occurs downstream, then resets when pressure equalizes. They eliminate the need for a complex bypass mechanism while reducing maintenance time.
