Pneumatic solenoid valve is an automation component that combines electrical signals with pneumatic control, used to control the on/off and flow direction of compressed air. The structure of pneumatic solenoid valve includes solenoid coil, pilot valve, main valve body, and sealing element. By powering on the electromagnetic coil and opening or closing the internal air circuit, precise control of pneumatic components such as cylinders and actuators can be achieved.
Selecting the correct valve actuator in today's modern industry can greatly affect the efficiency and performance of a system. Why pneumatic solenoid valve is becoming increasingly popular in various industries is due to its structural characteristics, advantages, and wide range of application industries.Pneumatic solenoid valves are serving as the most essential pneumatic directional component in industrial automation control
Pneumatic solenoid valve is a kind of solenoid valve,features of fast response, compact structure, easy control, and strong adaptability. They are widely used in industries such as automation equipment, mechanical manufacturing, packaging, textiles, automobiles, food, electronics, and chemicals. They are indispensable control core components in modern industrial pneumatic systems.
Pneumatic solenoid valves control the on/off and flow direction of compressed air through electrical signals, thereby driving pneumatic actuators.So they are commonly called air operated valve.
Their components that combine electrical signals with pneumatic fluids control, used to control the on/off and flow direction of compressed air. Solenoid pneumatic valve has the characteristics of fast response, compact structure, easy control, and strong adaptability. They are widely used in industries such as automation equipment, mechanical manufacturing, packaging, textiles, automobiles, food, electronics, and chemicals. They are essential control core components in modern industrial pneumatic systems.
Solenoid valve pneumatic enables multi-port directional control and is specifically used to drive pneumatic actuators.Other advantages as follows:
Fast response: Due to its electronic control, it can instantly control the airflow when powered on

◆ Implement automated operations such as sequential control, logical control, interlocking control, etc.
Whether a pneumatic solenoid valve is used solely for controlling compressed air or for mixed media applications including water, oil, and steam, it can adopt either of two actuation methods: direct-acting or pilot-operated. These two methods differ in both structure and application.
2 ways pneumatic solenoid valve include:2-way is the simplest control type of pneumatic solenoid valve, used only to control the on and off of compressed air.
3 ways pneumatic solenoid valve include:A typical 3/2 pneumatic solenoid valve has one inlet port, one exhaust port, and one outlet port. It comes in normally open and normally closed configurations, is usually single-coil controlled, features a compact structure, and is mostly pilot-operated.
4 ways pneumatic solenoid valve include:The main type is a 4-way 2-position pneumatic solenoid valve, with one inlet port, one exhaust port, two working ports, and two operating positions. There are also 4-way 3-position pneumatic solenoid valves with three operating positions.
5 ways pneumatic solenoid valve include:The main type is the 5-way 2-position pneumatic solenoid valve, but there are also 5-way 3-position types. Both have one inlet port, two working ports, and two exhaust ports, allowing airflow switching. They are generally used to control double-acting cylinders.
2-position valve
3-position valve
Normally Open
Normally Closed
pneumatic single solenoid valve:Only one solenoid coil operates, and when power is off, it resets by a spring.
double pneumatic solenoid valve:When two solenoid coils operate, the valve maintains its switched position and does not automatically reset.
Festo:High precision, modularity, intelligent control, and industrial automation,suitable for high-end manufacturing industries such as automotive and electronics.
SMC:Compact design, high cost-performance ratio, and strong versatility,ideal for automation equipment and general industrial applications.
Asco:Industrial-grade practicality, high reliability, explosion-proof, corrosion-resistant, and large flow capacity,well-suited for petrochemical, energy, and fluid control industries.
Direct-acting:The solenoid coil directly controls the valve core to open or close the air passage.
Pilot-operated:The main valve core is driven by air pressure to switch the main airflow direction, requiring a minimum operating pressure.
Servo-assisted:Compared to purely direct-acting valves, it saves solenoid coil power; compared to purely pilot-operated valves, it can start at lower pressure.
The design of air compressor soleoid valve is specifically designed for controlling compressed air media, and the following are industries that extensively use compressed air as a power source
Industrial manufacturing automation: assembly lines, robotic arms
Control packaging equipment: sealing, packaging, labeling, etc
Automotive manufacturing: welding, conveying, testing equipment
Food and beverage: automatic filling, coding, and handling
Electronic manufacturing: SMT surface mount, testing equipment
