Valves are set, tested, locked, and tagged with the set pressure, and certificates of the test are included.  Pre-set Swagelok relief valves are ready to be installed in the field without additional bench testing or calibration.  Our stringent quality process ensures you receive a safe and reliable product that enables you to save both time and resources, and minimize downtime.
