Describe the advantages and installation and maintenance details of the pneumatically regulated butterfly valve

Pneumatically regulated butterfly valves are available in flanged and clip-on versions. It is an important execution unit in the field of industrial automation control. The pneumatically regulated butterfly valve is mainly suitable for the control of pipeline flow, pressure and temperature in various industrial automation production. For example: electricity, metallurgy, petrochemical, environmental protection, energy management, fire protection systems. Pneumatically regulated butterfly valves are a category of pneumatic valves and pneumatic regulating valves.
The advantages of the pneumatically regulated butterfly valve are as follows:
1. Easy and quick opening and closing, labor saving, small fluid resistance, and can be operated frequently;
2. Simple structure, small size and light weight;
3, can transport mud, the minimum accumulation of liquid in the pipe mouth;
4, under low pressure, can achieve a good seal;
5, the adjustment performance is good.
The following items should be noted for the installation and maintenance of the pneumatic adjustment butterfly valve:
1. During installation, the pneumatic butterfly valve flap should be stopped at the closed position;
2. The opening position should be determined according to the rotation angle of the pneumatic butterfly valve plate;
