Direct acting solenoid valves are used to control the flow of fluid and gas media. The most common types of flow control are opening, closing, selecting different media or diverting a media.
A direct acting solenoid flow control valves shifts via an electric coil. When energized, it creates a magnetic field that moves a metal poppet. The direct action of energizing and de-energizing the solenoid controls the flow of the media, turning it on and off.
The advantage of a direct acting solenoid is that there is no minimum pressure requirement. The disadvantages are limited flow capability and high power consumption.
