In 1934, the COOPER foundry developed the first successful technique to pour 304 stainless steel. Since then we have grown to manufacture the highest quality stainless steel and exotic alloy valves on the market utilizing many grades of some of the hardest materials to work with such as: Stainless Steel, Austenitic Stainless, Duplex, Alloy 20, Monel, Moly, Hastelloy, Inconel, Nickel, Cobalt, Titanium, and Zirconium. We’ve been able to accomplish this through a combination of advanced design engineering, metallurgical science, technical know-how, and rigid quality control. Over the years, COOPER Valve patterns have been continually refined, hand-in-hand with increasing foundry technology allowing us to produce the finest quality cast and forged valves regardless of material composition.

In August 2011, Platform Management acquired the stock and general partner control interest in COOPER® Valves LP (“COOPER®”) from Newco Valves dba Newmans, a company of Cameron International.
