IVI is a VR certified safety valve repair facility, approved by the National Board of Boiler and Pressure Vessel Inspectors as a VR certificate holder (stamp 179). We certify pressure relief valves in the shop and in the field for sections V and UV. We also perform on-site testing (while the plant operates) providing documented reports for all valves tested. We are also certified to administer special process conversions regarding machining, welding, heat treating, and N.D.T. (non-destructive testing) with our VR certificate.

IVI is certified in service mediums such as air, liquid, steam and gas service.

With our VR stamp, we repair all types of pressure relief valves such as Consolidated, Crosby, Kunkle, Farris, Spence, Anderson Greenwood, Leser and numerous other O.E.M. safety and pressure relief valves.
