The direct-acting solenoid valve operates by directly driving the spool through an electromagnetic coil. It features a simple structure, fast response, and is best suited for small-caliber and low-pressure applications.
Pilot-Operated Solenoid Valve for High-Pressure Use
The pilot solenoid valve functions by opening a small channel through the pilot valve, creating a pressure difference between the upper and lower chambers of the main valve spool. This allows it to handle larger calibers and high-pressure applications while maintaining excellent sealing performance.
