We at Kerotest produce American-made valves that are among the best you can buy anywhere in the world. As an employee-owned TQM company, we don’t just talk about quality, we produce it. That’s why everyone here is empowered to give you the best product, the best value, and the best service. It’s the American way…and it’s our way. In a new multi-million dollar facility, we have combined good old American know-how with state-of-the-art technology.
