APPLICATION DESCRIPTIONschema

When the Push Button Valve #3517 (Item #2) is pressed, it sends a momentary air signal to the Directional Control Valve #3403 (Item #3). Supply air going to #3403 is then directed to the Dual Function Control Head #2544 (Item #1). The Control is now at Station #1.

When the Push Button Valve #3517 at Station #2 is pressed, it sends a momentary air signal to the Directional Control Valve #3403. Supply air going to Station #1 is automatically re-directed to the Dual Function Control Head #2544 at Station #2. The Control is now at Station #2.
