Compressed Air Safety ValvesCompressed Air Safety Valves

Our air safety valves are ASME regulated, National Board Certified Safety valves, Section I (V) and VIII (UV) rated for steam, air, gas and liquid applications. Valves are interchangeable with all safety valve manufacturers and available with the full array of trimming, seating and options. All products go through rigid quality control: we set, test and re-test to each customized application prior to the code stamping process.

A safety valve (also called relief valve) is a valve mechanism for the automatic release of air from a pressure vessel when the pressure exceeds preset limits. UV stamped, factory set and sealed. Choose for a variety of applications.
