Cooperative working principle
Control link:
PLC/ controller → Solenoid valve electrical signal → compressed air channel switching → pneumatic actuator action (on/off/adjust).
Typical process:
The solenoid valve gets power, switches the gas path, and the compressed air enters the actuator chamber;
The pressure pushes the piston/diaphragm, resulting in mechanical displacement;
After power failure, the solenoid valve is reset, the gas is discharged, and the actuator returns to the initial position (spring return or reverse gas supply).
Key performance parameters
Voltage compatibility: DC 24V (commonly used in industry), AC 220V (high-power scenario).
Response time: ≤50ms (high speed valve can reach 10ms, affecting the actuator frequency).
Working pressure range: 0.2~1.0MPa (general type), high pressure valve support 10MPa.
Protection class: IP65 (dustproof and waterproof) suitable for harsh working conditions.
Cycle life: ≥10 million times (high reliability industrial design).
