Check Valves and Excess Flow Valves

Check Valves

Swagelok offers a broad line of adjustable and fixed cracking pressure check valves to control back flow in general-service and high-purity applications.

Check valves:

  • Are designed to allow fluids to flow in one direction only
  • Are rated for use in medium- and high-pressure applications


Excess Flow Valves

  • Stop the uncontrolled release of system media when a downstream line ruptures
  • Reset automatically when pressure is restored
  • Reduce maintenance time
  • Eliminate the need for complex bypass mechanisms
