The advantages of electric and pneumatic valves:ġ. Pneumatic valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media. As there are more and more control methods and means, there are also many methods used to control pneumatic actuators in actual industrial life and industrial control.

The specific working principle can refer to the working principle of the double-acting pneumatic actuator. The five-way valve has five channels for ventilation, of which one is connected to the air source, and two are connected to the double The inlet and outlet ports of the outer chamber of the acting cylinder are connected, and the two are connected with the inlet and outlet ports of the inner chamber. The two positions are controllable in two positions: on-off. The two-position five-way solenoid valve is usually used in conjunction with a double-acting pneumatic actuator. Direction, according to the requirements of the load (valve) rotation torque, the cylinder combination can be adjusted to drive the load (valve) to work. The compressed air disk is sent to each cylinder, and the air inlet and outlet positions are changed to change the spindle rotation. The compressed air is used to push the multiple sets of combined pneumatic pistons in the actuator to move, and the force is transmitted to the crossbeam and the characteristics of the inner curve track to drive the hollow spindle to rotate.

Pneumatic valves are valves driven by compressed air. The electric valve uses electric energy as power to drive the valve through an electric actuator to realize the switching action of the valve, so as to achieve the purpose of switching the pipeline medium.

It can be divided into upper and lower parts, the upper part is the electric actuator, and the lower part is the valve. To put it simply, the editor of Power Transmission Exhibition is to use an electric actuator to control the valve to realize the opening and closing of the valve. Electric valves usually consist of electric actuators and valves.
