Series 27A

The CMO 27A Double Flange Butterfly Valve is a robust concentric butterfly valve designed for reliable isolation and flow control in water supply and industrial pipeline systems. Engineered for dependable bidirectional sealing and efficient flow performance, the 27A Series is ideal for water treatment, pumping stations, irrigation systems, HVAC networks and general industrial applications. Manufactured with a durable ductile iron body and corrosion-resistant disc options, the valve offers excellent mechanical strength and long service life in demanding operating environments. Its double flanged body design provides secure installation between pipeline flanges while improving alignment and stability in larger diameter systems. The 27A Series features a streamlined concentric disc profile that minimises pressure loss and turbulence within the pipeline, improving hydraulic efficiency and reducing energy consumption across the system. The resilient seat arrangement provides 100% watertight bidirectional sealing, ensuring reliable shut-off performance during repeated operating cycles. Designed for water distribution and industrial process applications, the valve is suitable for handling water, chilled water, heating water and other compatible non-aggressive media. The compact design and low operating torque also make the valve suitable for automated operation. Operating temperatures vary depending on seat material selection, with standard EPDM seated versions typically suitable for temperatures from -10°C to +90°C. Specialist seat materials are available for higher temperature industrial applications and more demanding operating conditions. The CMO 27A Series is available in a wide range of sizes and can be supplied with gearbox, pneumatic or electric actuation options depending on system requirements. ISO mounting compatibility allows straightforward actuator installation for automated process control systems. Manufactured and hydrostatically tested to stringent quality standards, the valve delivers reliable sealing performance and long operational life in municipal and industrial water systems. Held in stock at Ultravalve and competitively priced, the CMO 27A Double Flange Butterfly Valve provides a reliable and cost-effective solution for industrial and water flow control applications.
