Meeting Ever-Increasing Industry Demands for More Than 100 Years.

KEROTEST VALVES are among the best you can buy anywhere in the world. As an Employee Stock Ownership Plan (ESOP) company, we don’t just talk about quality, we produce it, because everyone here is empowered to give you the best product, the best value and the best service.

Kerotest Manufacturing Corp. is a leading supplier of valves and related equipment to the worldwide energy markets, including natural gas distribution, oil & gas drilling, nuclear fuel, and the municipal water market. Established in PITTSBURGH, PENNSYLVANIA in 1909, our headquarters remains here along with our product development, engineering, manufacturing and customer service operations. In 1989, we opened a strategically located manufacturing facility in MANSURA, LOUISIANA for the production of Kerotest instrumentation valves and polyethylene ball valves. The location gives us ready access to our customers throughout the United States.

2019 will bring further expansion in Mansura with the introduction of a 30,000 square foot state-of-the-art development, manufacturing and testing facility.

As our nation’s energy distribution networks continue to require repairs, upgrades and expansions, trust Kerotest to continue manufacturing the valves and equipment that meet those needs.
