Pneumatic actuator butterfly valve

With the development and progress of the economy, our company's pneumatic actuator butterfly valve products are also being updated and upgraded. Their specifications are as follows:

The main advantages of pneumatic butterfly valves are simple structure, small volume, light weight, and low cost. Pneumatic butterfly valve; The characteristics are particularly evident. Installed on a high-altitude underground passage, it is easy to control and operate a two position five way solenoid valve, and can also adjust the flow medium. Low fluid resistance, excellent flow area when the medium to large diameter pneumatic butterfly valve is fully opened, fast and effortless opening and closing, and can be completed by rotating the disc 90 degrees. Due to the nearly equal force of the butterfly hand medium on both sides of the shaft, the torque direction is opposite, the opening and closing torque is small, and the sealing performance is good under low pressure. Butterfly valve sealing materials include nitrile rubber, rubber, and edible rubber, which have good liner sealing performance. Among them, the hard sealed butterfly valve is made of soft and hard laminated metal sheets, which have the advantages of metal hard sealing and elastic sealing, and have excellent sealing performance under low temperature conditions.
