The Cast Iron Grooved Signal Butterfly Valve is a versatile and reliable valve used extensively in various industrial applications. This valve combines the durability of cast iron with the functionality of a butterfly valve, making it an ideal choice for controlling fluid flow.

Structure and Design

The design of this valve features a disk-shaped closure member, known as the butterfly plate, which rotates around a valve axis to open and close the valve. The valve body is made of cast iron, ensuring strength and resistance to wear and tear. The grooved signal feature allows for easy installation and maintenance, enhancing its overall usability.

Application Range

Cast Iron Grooved Signal Butterfly Valves are commonly used in pipelines in industries such as coal chemical processing, petrochemicals, rubber manufacturing, papermaking, and pharmaceuticals. They serve as either diversion, confluence, or flow direction switching devices, making them essential components in fluid handling systems.

Performance Parameters

These valves have a nominal diameter range of DN50mm to DN300mm and can operate within a temperature range of -29°C to 300°C. This wide range of parameters allows them to be used in a variety of environments and conditions.

Operational Characteristics

The opening and closing of the valve are smooth and require minimal effort. The relationship between the valve’s opening and fluid flow is linear, making it easy to control and regulate fluid flow rates. Additionally, the valve’s design minimizes the risk of leakage and ensures a tight seal.

Conclusion

In summary, the Cast Iron Grooved Signal Butterfly Valve is a robust and reliable valve suitable for a wide range of industrial applications. Its design, performance parameters, and operational characteristics make it an excellent choice for controlling fluid flow in various systems.
