Preface
In the field of modern industrial automation, solenoid valves are the core actuators of fluid control systems. Their performance and reliability directly determine the operating efficiency and safety level of the entire system. Parker solenoid valves have become the most competitive preferred solution/ideal choice in many industrial applications with their leading technological advantages and wide industry adaptability.

Working Principle
Parker solenoid valve works based on the principle of electromagnetic induction:
Power-on state: The coil excitation generates electromagnetic force, attracting the valve core to move and open the flow channel, and the medium flows.
Power-off state: The electromagnetic force disappears, and the valve core closes the flow channel through spring reset (or medium pressure assistance) to cut off the medium.
*Note: Depending on the structural differences, the reset method may include spring force, medium pressure difference or gravity synergy. *
Model classification
| Type | Working principle | Features and applicable scenarios |
|---|---|---|
| Direct acting | Electromagnetic force directly drives the valve core | Simple structure, fast response (≤3ms), zero pressure difference start; diameter ≤25mm, suitable for high-precision control scenarios of small gas/liquid systems |
| Step-by-step direct acting | Electromagnetic force opens the pilot hole, and the pressure difference drives the main valve core | Zero pressure difference start, high driving force requirement; horizontal installation required; suitable for medium flow control scenarios |
| Pilot type | The pilot valve controls the main valve cavity pressure, and the pressure difference drives the main valve core | Low power consumption, large flow; wide applicable pressure range, commonly used in industrial hydraulic systems |
