Vacuum Valve Technology Direct Acting 2/3 Way Vacuum Solenoid Valve MO
1. Introduction and application
- The three-way vacuum electromagnetic valve is a two-position direct acting, conical valve core, normally open or normally closed type.
- This valve is commonly used in vacuum cut-off of feeders, suctiontype stackers, robots, openers, etc. where it is necessary to react quickly between the suction in the line and the intake air, and can also be vacuum connect in the case of power loss or no air pressure;
- As the pressure difference is small, the valve cannot normally switch the hole position and cannot be used in low vacuum.
- The valve has no friction and internal dynamic stress, fast response speed and a long service life.
2. Design

- The body is made of aluminum alloy.
- Solenoid valve controls piston action.
- When the valve is used normally open, (1) is the vacuum pump interface, (2) is the pressure relief port, and (3) is the action port.
- When the valve is used as a normally closed, (1) is the pressure relief port, (2) is the vacuum pump interface, and (3) is the action port.
