The company began performing valve repairs in 1992, and today the division has grown to offer numerous services. Coupled with the experience and expertise of other company divisions, our service team has a "well rounded" understanding of quality valve repairs.

We have received National Board Certification for the repair and testing of safety valves both at our facility and in the field. The company made a significant investment by installing a modern test lab with all necessary features to guarantee quality results. We also have the equipment for on site valve testing so the plant can remain on line. Reports are furnished for insurance, incpector or corporate requirements.
