Benefits Of Pneumatic ventilation wafer butterfly valve:
The pneumatic ventilation butterfly valve is a gas medium control device powered by compressed air. It is mainly used for regulating and cutting the gas flow in industrial pipeline systems such as building materials, metallurgy, and power. This valve adopts a mid-line butterfly plate and short structural steel plate welding design, featuring a compact structure, low flow resistance, and large flow capacity. It realizes the control of gas flow by rotating 90° and is suitable for horizontal or multi-position installation.
Features Of Pneumatic ventilation wafer butterfly valve :
1). Nominal diameter range: DN50 - DN350, nominal pressure ≤ 0.6 MPa, in compliance with national standards such as GB/T 12238.
2). The features of low resistance and large flow capacity, with small operating torque, quick and effortless opening and closing.
3). Use appropriate materials to meet the requirements of different medium temperatures (low, medium, and high) as well as corrosive media.
