OCECO was the first supplier of a complete line of venting and tank fitting equipment. In fact, our name "OCECO" is an abbreviation for Oil Conservation Engineering COmpany! OCECO was the first to develop a double disc water draw off valve and a pressure balanced membrane seated vent valve. Both valves were developed to prevent freezing up along with their normal functions. OCECO's modular vent valves are the most versatile, high performance valves on the market today.
