The Difference between Direct Acting Solenoid Valve and Pilot-Diaphragm Solenoid Valve

The solenoid valve can be divided into direct acting and pilot-diaphragm according to the driving mode. The direct acting drive solenoid valve is driven by electromagnet to control the flow through and off. The first drive solenoid valve is driven by electromagnet to control the flow of a small flow of fluid. This small flow of fluid controls the movement of the main valve core.
