Vacuum Components

one way valve

One Way Valve;
The purpose of the one way valve is to only let air through one way. By blowing on one end, the air pushes the valve open and the air can flow. Blowing on the other end, the air, and the spring push the valve shut, not letting any air through.

Linear Solenoid;

linear solenoid valve

The purpose of this linear solenoid valve is to only let air through when an electrical current is applied. when no current is applied, the passage is blocked off and no air can flow. When a current is applied to the windings, the solenoid pulls the valve off its seat and then the air can flow.

Vacuum diaphragm valve

Vacuum diaphragm operated valve;
The purpose of this valve is to only allow air to flow when there is no vacuum applied. Without vacuum, the air is free to flow between the hoses. But when a vacuum is applied, the diaphragm moves and causes the passage way to be blocked so no air can flow through the hoses.
