Pneumatic butterfly valve in our life has an important role is to use with the stem rotation of the circular disc to do the opening and closing to achieve the action of the pneumatic valve to do the main cut-off valve can also be designed to have the regulation or paragraph valve And adjust the function, the current valve in the use of low-pressure large and medium-diameter pipe more and more.
The main advantages of pneumatic butterfly valve:
1, compact and lightweight, easy disassembly and maintenance, and can be installed in any location. Pneumatic butterfly valve
Pneumatic butterfly valve
2, the structure is simple, compact, small operating torque, 90 ° turn quickly open.
3, the flow characteristics of the trend line, adjust the performance.
4, butterfly plate and valve rod connection pinless structure, to overcome the possible internal leakage point.
5, the use of spherical disc butterfly shape, improve the sealing performance and extend the service life of the valve, open more than 50,000 times the pressure remains zero leakage.
6, seals can be replaced, and sealed to achieve two-way seal.
7, butterfly board can be sprayed coating according to user requirements, such as nylon or PTFE.
8, pneumatic butterfly valve can be designed to connect flange and the folder.
