Product Overview
The Resilient Seat Flap Type Valve is a high-performance flow control solution engineered for demanding water and neutral oil applications. Designed with a ductile iron body (Model 2311) and a fully rubber-lined resilient seat, this valve delivers exceptional leakproof performance and long-term corrosion resistance across a wide size range from DN50 to DN1000.
Key Features & Advantages
- Superior Leakproof Design: The resilient rubber seat completely encapsulates the valve disc, ensuring zero leakage at the seat-face seal even under full-rated pressure of 16kg/cm².
- Corrosion Resistance: 100% Fusion Bonded Epoxy (FBE) coating is applied to both inner and outer surfaces, meeting AWWA C550 standards. This dual-layer protection effectively prevents rust and chemical degradation in aggressive environments.
- Robust Construction: Manufactured from high-grade Ductile Iron (GJS-500-7 / ASTM A536 65-45-12), offering impact strength far superior to conventional grey cast iron valves.
- Full Bore Flow Path: The flap-type design minimizes flow resistance and pressure drop, maximizing pumping efficiency and reducing energy costs.
- Low Maintenance: The flap disc mechanism features a self-centering design with minimal moving parts, significantly reducing wear and extending service intervals.
