Series 23D

The CMO 23D Double Flange Butterfly Valve is a robust concentric butterfly valve designed for reliable regulation and isolation in water supply and industrial pipeline systems. Engineered for low pressure loss and dependable bidirectional sealing, the 23D Series is ideal for water treatment, plumbing, irrigation, pumping stations and general industrial applications. Manufactured with a durable ductile iron body and fitted with a vulcanised resilient seat, the valve provides excellent corrosion protection by preventing direct contact between the fluid and the cast iron body. This design improves operational lifespan while maintaining reliable sealing performance in demanding environments. The streamlined hydrodynamic disc profile minimises head loss and improves flow efficiency throughout the system. The valve also delivers 100% watertight bidirectional sealing, making it suitable for a wide range of water and industrial flow control applications. Polished disc edges help protect the seat from wear and improve long-term reliability during repeated operating cycles. Its double flanged design allows secure installation directly between pipeline flanges without the need for additional gaskets, simplifying installation and reducing maintenance requirements. The valve is compatible with PN10, PN16 and ANSI 150 flange standards and is available in sizes from DN50 up to DN1000. Operating temperatures typically range from -10°C to +90°C with standard EPDM seat materials. Operating temperatures vary depending on seat and sealing material selection, with specialist configurations available for more demanding industrial applications. The CMO 23D Series can be supplied with gearbox, pneumatic or electric actuation options, making it suitable for both manual operation and fully automated process systems. Manufactured and hydrostatically tested to stringent quality standards, the valve delivers reliable sealing performance and long operational life in industrial and municipal water systems. Held in stock at Ultravalve and competitively priced, the CMO 23D Double Flange Butterfly Valve provides a reliable and cost-effective solution for industrial and water flow control systems.
