Pneumatic butterfly valve

The pneumatic butterfly valve consists of a pneumatic actuator and a butterfly valve. The pneumatic butterfly valve is opened and closed with a circular disc rotating with the valve stem to realize the action of the pneumatic valve. It is mainly used as a shut-off valve, and can also be designed to have the function of adjusting or stepping valve and regulating. The butterfly valve is currently at low pressure. The use of large and medium caliber pipes is increasing.

The pneumatic butterfly valve consists of a pneumatic actuator and a butterfly valve. The pneumatic butterfly valve is opened and closed with a circular disc rotating with the valve stem to realize the action of the pneumatic valve. It is mainly used as a shut-off valve, and can also be designed to have the function of adjusting or stepping valve and regulating. The butterfly valve is currently at low pressure. The use of large and medium caliber pipes is increasing. Pneumatic butterfly valve classification: stainless steel pneumatic butterfly valve, hard seal pneumatic butterfly valve, soft seal pneumatic butterfly valve, carbon steel pneumatic butterfly valve. The main advantages of the pneumatic butterfly valve are simple structure, small size, light weight and low cost. This feature is especially suitable for pneumatic butterfly valves. It is installed in the high-altitude dark channel and is controlled by the two-position five-way solenoid valve. It can also adjust the flow medium.

 

  The main advantages of the pneumatic butterfly valve are simple structure, small size and light weight, low cost, and the characteristics of the pneumatic butterfly valve are particularly remarkable. It is installed in the high-altitude dark channel, and is controlled by the two-position five-way solenoid valve, and the flow medium can also be adjusted. The fluid resistance is small. When the large and medium-diameter pneumatic butterfly valve is fully open, the effective flow area is large, the opening and closing is quick and labor-saving, and the disc puller can rotate 90 degrees to complete the opening and closing, because the force of the disc-hand media on both sides of the rotating shaft is nearly equal, The generated torque direction is opposite, so the opening and closing torque is small, and good sealing can be achieved under low pressure. The butterfly valve sealing material is nitrile rubber, fluorine rubber, edible rubber, and lining PTFE, so the sealing performance is good, and the hard sealing butterfly valve is soft. The hard laminated metal sheet has the advantages of a hard metal seal and an elastic seal, and has excellent sealing properties at low temperatures.
