summary:Pneumatic butterfly valve is a newly developed long-life energy-saving butterfly valve by our company. The butterfly valve adopts a three-dimensional eccentric principle design and a new processing technology that is compatible with elastic sealing and hard soft multi-level sealing, making the butterfly valve reliable in sealing during operation and achieving airtight sealing without leakage. The eccentric design extends the service life of the valve. The pneumatic actuator adopts a curved arm conversion structure, which has the characteristics of large output torque, small volume, stable and reliable performance. When used in conjunction with valve positioners or solenoid valves, it can achieve proportional adjustment or switch control, and is suitable for media such as gases, solid particles, and liquids. It can be widely used in automation control systems for industrial sectors such as papermaking, petrochemicals, chemical engineering, metallurgy, power, environmental petroleum, light industry, and building automation.
