Pneumatic Ventilation Butterfly Valve, the sealing ring is made of the same material as the valve body, and is driven by a pneumatic actuator. The applicable temperature depends on the material of the valve body. The nominal pressure is generally less than 0.6Mpa, which is suitable for industrial, metallurgical, environmental protection and other pipelines for ventilation and regulating flow.
1. The design is novel, reasonable, unique in structure, light in weight, and quick to close.
2. The operating torque is small and convenient, labor-saving and light.
3. Using different materials to meet a variety of media and working conditions.
