What is a direct acting solenoid?

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.
