Series 11A

The CMO 11A Series Resilient Seat Gate Valve is a rising stem isolation valve designed for reliable shut-off performance in water distribution and industrial pipeline systems. Engineered for minimum head loss and 100% watertight sealing, the 11A Series is ideal for water treatment plants, pumping stations, fire protection systems, irrigation networks and industrial pipework applications. Manufactured with a durable GJS500 ductile iron body and bonnet, the valve provides excellent mechanical strength and long-term reliability in demanding operating environments. The resilient EPDM or NBR coated wedge ensures dependable sealing performance and smooth operation during repeated opening and closing cycles. The full bore design allows unrestricted media flow through the valve, reducing pressure loss and improving overall system efficiency. Its guided gate arrangement ensures accurate alignment and consistent sealing performance, while the rising stem design provides clear visual indication of valve position during operation. Designed for bidirectional flow, the CMO 11A Series is suitable for a wide range of clean and dirty water applications where reliable isolation is essential. The valve is WRAS certified for drinking water use and manufactured according to DIN 3352 standards, with hydrostatic testing completed in accordance with EN 12266-1 Class A requirements. The valve is available in sizes from DN50 to DN600 with RF PN10/16 flanged connections manufactured according to ISO 7005-2 standards. Face-to-face dimensions comply with EN 558 Series 14 specifications for easy integration into existing pipe systems. Operating temperatures range from -10°C to +90°C depending on seat material selection and application requirements. The valve is finished with a durable RAL 5015 epoxy coating for enhanced corrosion resistance and long service life in water and industrial environments. Held in stock at Ultravalve and competitively priced, the CMO 11A Resilient Seat Gate Valve provides a reliable and cost-effective solution for water distribution and industrial isolation applications.
