Dampers & Air and Gas Valves

CMO Valves manufactures and designs a wide selection of damper equipment in a variety of sizes and valve types for air and gas applications. Engineered to deliver optimal performance, CMO damper valve solutions serve to regulate gas flow within pipelines, providing isolation and precise control when necessary. Standard tightness rate for CMO Valves ranges between 97% and 100% depending on the seal design. 100% tightness is made possible by air injection sealing with a double clapper system where needed for applications that require watertight integrity. All valves are tested hydrostatically at CMO Valves and material and test certificates can be provided.
