Directional Control for Pneumatic Valves

In order to adequately control both speed and sequence of an operation, directional-control valves are necessary. This becomes even more vital when working with pneumatic circuits that direct/block airflow. Control valves are built with multiple valve positions, ports, and flow paths. The flow paths that are beneath different operations determine the requirements for ports and valve positions. Although pneumatic control valves are customizable based on specific applications, there are still several basic configurations that customization will be based on.

A two-position valve comes in three separate types: Two-way, two position; Three-way, two position; and four-way, two position. The simplest version is designed as an on-off function that connects different parts of a system. As the design gets more complex, more operational options become available.

The other standard option is a four-way, three position pneumatic controller. These valves are used to control the motion/movement of an actuator. For instance, when placed in a centered position, the controller can lock an actuator.

During the consideration process of building pneumatic systems, never neglect the importance of directional pneumatic valves. Speaking with local companies will allow you to design a system from the ground up, meaning that you'll get a system that is customized for specific functions.
