Series 25A

The CMO 25A Grooved Butterfly Valve is a lightweight concentric butterfly valve designed for reliable isolation and flow control in grooved piping systems. Engineered for quick installation and dependable sealing performance, the 25A Series is ideal for HVAC systems, water distribution, fire protection networks, cooling systems and general industrial applications. Manufactured with a durable ductile iron body and available with high-quality disc and seat material options, the valve offers excellent mechanical strength and corrosion resistance for long-term operation in demanding environments. Its grooved-end design allows rapid installation into grooved pipe systems, significantly reducing installation time and maintenance costs compared to traditional flanged connections. The 25A Series provides reliable bidirectional sealing and efficient flow performance with minimal pressure loss. The streamlined concentric disc design improves hydraulic efficiency while reducing turbulence throughout the pipeline system. Compact construction and lightweight design also make the valve particularly suitable for commercial building services and space-restricted installations. Designed for use in HVAC, chilled water, heating and industrial water systems, the valve is suitable for handling water, water with glycol mixtures and other compatible non-aggressive media. The resilient seat arrangement ensures dependable shut-off performance during repeated operating cycles. 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 25A Series is available in a range of sizes and can be supplied with lever operation, gearbox, pneumatic or electric actuation options depending on system requirements. ISO mounting compatibility also allows straightforward automation and actuator integration. Manufactured and hydrostatically tested to stringent quality standards, the valve delivers reliable sealing performance and long operational life in commercial and industrial piping systems. Held in stock at Ultravalve and competitively priced, the CMO 25A Grooved Butterfly Valve provides a reliable and cost-effective solution for HVAC and industrial flow control applications.
