Pneumatic systems use a wide variety of components to control the amount of air, the rates, and the pressure with which it moves through the systems. One of the components used is . Here are some types of these valves.
2-way directional valve: as you can gather from the name, this valve moves airflow in two separate directions. Both ports have the ability to be opened or closed depending on what you need done.
3-way valve: each of the ports on this valve serves a specific function (unlike like the 2-way). The first port is for airflow intake, the second is for an exhaust, and lastly there is the port to connect two deceives.
Spring Offset: How the direction of the airflow is switched is what classifies this kind of pneumatic valve. As an example, the valve is either closed or open in a two-way directional valve, so airflow is either prevented or enabled. A valve spool is moved into position by an actuator which allows a port to assume a closed or open position.
