Pneumatic soft seal Wafer butterfly valve
Product features
Pneumatic butterfly valve is a specially designed and carefully manufactured product based on the introduction of advanced foreign technology. The butterfly valve is equipped with a stroke limit switch, a solenoid valve, a triple piece and a 0.4-0.7MPa air source to achieve switching operations, and sends two pairs of passive contact signals to indicate the valve's switching. When using intelligent control and positioning, it is matched with a domestic electric valve positioner and inputs a 4-20mADC signal and a 0.4-0.7MPa air source to realize intelligent control and adjust parameters such as pressure, flow, temperature, and liquid level. It is powered by compressed air, and the valve stem drives the valve core to rotate 90°C in the valve body, which can achieve fully open-fully closed actions. This product is divided into metal seal and soft seal according to its sealing performance. It has the advantages of compact structure, small size, reliable operation, good sealing, easy maintenance, convenient installation and strong adaptability. It can be widely used in industrial automatic control systems such as petroleum, chemical industry, light industry, pharmaceuticals, papermaking, automobiles, etc. for remote centralized control or local control.
