Structure & Mechanism
Solenoid driven valve can be used for gas or liquid control, and features normal operation under conditions of Vacuum, Zero or Negative Pressure. But the valve size is usually smaller than 25mm of sluid tube.
Solenoid Valves' Structure & Mechanism,
Our current solenoid valves are mainly of direct acting piston or diaphragm structure. See one sample mechanism:
Picture B：When solenoid/coil is energized, its magnetic force pulls closing member （plunger）down，then orifice A is opened and A,P is through/connected, while orifice B is closed;
Picture A：When solenoid/coil is de energized, the spring push up the closing member, then orifice B is opened and B,P is through/connected, while orifice A is closed.
