Product Description

Product Description

D641-10C Pneumatic Flanged Butterfly Valve with actuator and limit switch is a high-performance control valve for reliable on-off and regulation in pipelines. Its double eccentric structure minimizes friction, enhancing longevity and stability. Crafted from high-quality cast steel, it offers high strength, pressure resistance, and corrosion resistance, ideal for harsh conditions. The flange connection design facilitates easy installation, disassembly, and maintenance.

This pneumatic butterfly valve is versatile for water treatment, petroleum, chemical, electric power, metallurgy, HVAC, and more, handling water, gas, oil, steam, and non-corrosive or mildly corrosive media. The standard pneumatic actuator enables fast, stable, and low-noise automatic operation for frequent use. The limit switch provides precise valve position feedback for remote monitoring and integration with control systems, boosting pipeline automation and management efficiency.

The product has the advantages of compact structure, small flow resistance, good sealing performance, stable operation and long service life. It can meet the needs of different working conditions and can be customized according to customer requirements for different pressure levels, calibers and matching actuators. Each valve is strictly inspected and tested before leaving the factory to ensure stable performance, safe and reliable operation, and is an ideal choice for industrial pipeline automatic control.
