Product Description

Ductile iron butterfly valves are widely used in industrial pipeline systems to regulate and cut off fluid flow. Their main body is composed of ductile iron, which is known for its excellent mechanical strength, impact resistance, and corrosion resistance. Compared to traditional cast iron, ductile iron has excellent durability and flexibility, making it an ideal choice for high-pressure and heavy-duty applications. Due to their reliability and cost-effectiveness, these valves are commonly used in water treatment, chemical processing, HVAC systems, oil and gas pipelines, and fire protection systems.

The advantages of ductile iron butterflyvalves are compact structure, light weight, and easy installation and maintenance, which can also reduce downtime during operation. In addition, they come in various configurations, including valve discs, lugs, and flange types, to accommodate different pipeline requirements. The internal components of a valve, such as the disc, stem, and seat, are designed to ensure tight sealing and smooth operation, minimizing leakage even under high pressure conditions.

Working principle

The working principle of ductile iron butterfly valve valve is actually very simple, mainly controlling the flow of fluid by rotating the valve disc. The valve disc is like a circular plate, installed inside the valve body. When you rotate the valve stem, the valve disc will also rotate, opening or closing the valve. The angle of the valve disc determines the flow rate of the fluid. If the valve disc is fully opened, the fluid can flow smoothly and unobstructed; If the valve disc is closed, the flow of fluid can be completely cut off. The ductile iron material makes this valve both sturdy and durable, suitable for use in various industrial pipelines, especially in environments that require corrosion resistance and high strength.For industries requiring precise flow control, ductile iron butterfly valves with pneumatic, electric, or hydraulic actuators can be integrated into smart control systems, enabling remote operation and real-time monitoring.
