Product Description
Wafer-type Large Diameter Butterfly Valve
This high-performance wafer-type large diameter butterfly valve is engineered for demanding high-flow media control applications. Manufactured from high-strength ductile iron, it delivers exceptional durability and cost-effectiveness while withstanding high pressure and heavy loads.
Core Advantages and Features
- Robust and Durable Valve Body Material: Constructed from ductile iron with superior mechanical properties compared to standard gray cast iron. Provides strength close to steel, excellent impact resistance, and exceptional toughness for pressure fluctuations and external stresses in large-diameter pipeline systems.
- Optimized Structural Design: Compact wafer-type design saves installation space and cost. Precision-engineered disc and stem enable low-torque operation for smooth opening and closing.
- Reliable Sealing Performance: Equipped with high-performance resilient seats (EPDM or NBR) ensuring bidirectional bubble-tight shut-off. Suitable for water, air, oil, and other neutral media.
- Broad Application Adaptability: Ideal as a reliable shut-off or regulating device in large-diameter pipelines across municipal water supply, power plants, industrial circulating water systems, HVAC, and wastewater treatment.
- Multiple Actuation Options: Compatible with manual gear operators, electric actuators, or pneumatic actuators to meet diverse automation control requirements.
