Main features and differences between pneumatic butterfly valve and electric butterfly valve

The main features of pneumatic butterfly valves are:

1. Gear-type double piston, large output torque and small volume;

2. Rack connection can adjust the opening angle and rated flow;

3. The actuator can be optionally provided with a signal feedback instruction and various accessories to achieve automatic operation;

4. IS05211 standard connection provides convenience for product installation and replacement;

5. The cylinder is made of aluminum and gold material, with light weight and beautiful appearance;

6. Manual operation mechanism can be installed on the top and bottom;

7. The adjustable screw at both ends can make the standard product have an adjustable range of 4 ° at 0 ° and 90 °, ensuring synchronization accuracy with the valve.


      The main features of electric butterfly valves are:

     1. Novel design, reasonable, unique structure, light weight, quick opening and closing.

     2. The operating torque is small, the operation is convenient, and the labor-saving and dexterous.

     3. Use suitable materials to meet low, medium and high medium temperature and corrosive medium.

     The electric adjustment butterfly valve is made of the same material as the valve body into a sealing ring, and adopts electric or pneumatic transmission. The applicable temperature depends on the material selection of the valve body, and is generally suitable for industrial, metallurgical, environmental protection and other pipelines for ventilation and media flow adjustment.
