Pneumatic high-performance sealed butterfly valve combines the advantages of ball valve and butterfly valve, with excellent cutting and regulating performance, compact structure, small volume, light weight, and easy maintenance. Suitable for production process control systems in industries such as petrochemicals, chemicals, metallurgy, power plants, and light industry.
The pneumatic high-performance sealed butterfly valve consists of a cylinder type actuator and a high-performance sealed butterfly valve. The butterfly plate and sealing mechanism adopt a unique eccentric design. The sealing surface of the butterfly plate only contacts the sealing surface of the valve seat at the moment of closure, and the sealing surface is almost frictionless during opening and closing. This not only reduces the opening and closing torque of the valve, but also improves its service life, making the sealing more reliable. There are two types of valve seat sealing: metal sealing and soft sealing.
