Series 11A-3

The CMO 11A-3 Resilient Seated Gate Valve is a specialist isolation valve designed for water distribution systems using polyethylene (PE) pipe connections. Engineered for reliable shut-off performance and minimum head loss, the 11A-3 Series is ideal for buried water pipelines, municipal water distribution, irrigation systems, pumping stations and industrial water applications. Designed with a resilient seated wedge and compact non-rising stem configuration, the valve provides dependable sealing performance while remaining suitable for underground installations and restricted spaces. The full bore design allows unrestricted media flow through the valve, reducing pressure loss and improving hydraulic efficiency across the system. Manufactured with a durable ductile iron body and corrosion-resistant epoxy coating, the CMO 11A-3 Series offers excellent mechanical strength and long-term durability in demanding underground and industrial environments. The resilient EPDM or NBR coated wedge ensures smooth operation and effective sealing performance during repeated opening and closing cycles. The valve is specifically designed for integration with PE pipe systems, providing secure and reliable connection performance for modern water distribution networks. Its robust construction and watertight sealing capability make it suitable for both clean water and general industrial service applications. Designed for bidirectional flow, the CMO 11A-3 Series provides reliable isolation performance while helping reduce maintenance requirements and operational downtime. The underground service configuration also supports operation through extension spindles and surface boxes where required. Operating temperatures typically range from -10°C to +90°C depending on seat material selection and application requirements. The resilient seated design helps ensure long service life and dependable sealing performance in water infrastructure systems. Available in a range of sizes and pressure ratings, the valve is suitable for PN10/16 systems and manufactured to recognised international standards for water industry applications. Manufactured and hydrostatically tested to stringent quality standards, the CMO 11A-3 Series delivers dependable operational reliability and long-term sealing performance in municipal and industrial water systems. Held in stock at Ultravalve and competitively priced, the CMO 11A-3 Resilient Seated Gate Valve provides a reliable and cost-effective solution for PE pipeline isolation and water distribution applications.
