Pneumatic butterfly valve products and features

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 that rotates 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 adjusting. The butterfly valve is currently at low pressure. More and more use on large and medium diameter pipes. 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 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. It can also adjust the flow medium.

Characteristics

1. Compact and lightweight, easy to disassemble and repair, and can be installed at any position.

2. The structure is simple and compact, the operating torque is small, and the 90° rotation starts quickly.

3. The flow characteristics tend to be straight and the adjustment performance is good.

4. The connection between the disc and the valve stem adopts a pinless structure, which overcomes the possibility of internal leakage.

5. The outer circle of the butterfly plate adopts spherical shape, which improves the sealing performance and prolongs the service life of the valve. It still maintains zero leakage when the pressure is opened and closed more than 50,000 times.

6, the seal can be replaced, and the seal is reliable to achieve two-way sealing.

7, the disc can be sprayed according to user requirements, such as nylon or polytetrafluoroethylene.

8. The valve can be designed as a flange connection and a clamp connection.

9, the drive mode can be selected manually, electric or pneumatic.
