Pneumatic actuators have good adaptability to the working environment, especially in harsh working environments such as flammable, explosive, dusty, strong magnetism, radiation and vibration, and are superior to hydraulic, electronic, and electrical control.

Compact structure and small size. Compared with pneumatic actuators, electric actuators are relatively simple in structure. A basic electronic system includes actuators, three-position DPDT switches, fuses and some wires, which are easy to assemble.

In fact, pneumatic systems and electric systems are not mutually exclusive. Pneumatic actuators can simply realize rapid linear circulation movement, simple structure, convenient maintenance, and can be used in various harsh working environments, such as explosion-proof requirements, dusty or humid ......

The electric centerline butterfly valve (concentric butterfly valve) adopts a centerline structure design. The center of the valve plate and the center of the valve body are concentric, that is, the shaft center of the valve stem, the center of the butterfly plate and the center of the valve body ar......

At the production site, after the control system is put into operation, various oscillations of the electric actuator are often encountered. Electric actuators and regulating valves are operating in an oscillating state, which will affect their service life. Therefore, the oscillation phenomenon sho......

The three-way ball valve has two-seat and four-seat sealing structures. The spool channel has two structural forms, L-type and T-type. The rotation angle of the spool is controlled to change the spool hole.The connection state of the channel and the pipe mouth can realize the different combination c......
