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 conditioning or segment valve and conditioning. Now the butterfly valve is at low pressure. There are more and more applications on large and medium diameter pipelines. 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. The characteristics of the pneumatic butterfly valve are particularly obvious. The device 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.
1, small and simple, easy to disassemble and repair, and can be installed in any orientation.
2. The structure is simple and compact, the operating torque is small, and the 90° reverse rotation is quick.
3. The flow characteristics tend to be straight and the conditioning performance is good.
4. The connection between the butterfly plate and the valve stem is selected without a pin 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. The pressure is kept open and closed more than 50,000 times and still maintains zero leakage.
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.
8. The valve can be designed to be flanged and clamped.
9. The driving method can be manual, electric or pneumatic.
