The use of pneumatic butterfly valve is also very wide. It can often be seen in our daily life, so we should fully understand its characteristics and the places that should be paid attention to when installing the device. Here is a brief description by Shanghai Gaocheng. We share the following:

The pneumatic butterfly valve consists of two parts: a pneumatic actuator and a butterfly valve body. It is mainly used for intercepting and throttling on the pipeline. The butterfly valve opening and closing member is a disc-shaped disc that rotates around its own axis in the valve body to achieve the purpose of opening and closing or conditioning.

The main features of the butterfly valve:

1, small and light, easy to disassemble and repair, and can be installed in a comfortable position.

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

3. The flow characteristics are straight and the conditioning 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 the spherical shape, which improves the sealing performance and prolongs the service life of the valve. It still adheres to zero leakage with the pressure opening and closing more than 50,000 times.

6. The seal can be replaced and the seal is firmly secured to the two-way seal.

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

The device and protection of the butterfly valve should pay attention to the following matters:

1. When the device is in use, the valve flap should be stopped in the closed position.

2. The open orientation should be determined according to the rotation angle of the disc.

3. Butterfly valve with bypass valve, open the bypass valve before opening.

4. The device shall be installed according to the manufacturer's instructions. The heavy butterfly valve shall be provided with a solid foundation.
