What is the purpose of the manual override button on a solenoid-operated pneumatic valve?

The manual override is a mechanical path to move the valve without the solenoid energizing. It lets you shift the valve spool manually, typically back to its de-energized (default) position, which is useful for testing, maintenance, or when electrical control isn’t available. In other words, the override provides a safety/diagnostic way to reset or position the valve by hand, not to energize the solenoid, change polarity, or report position to a controller. Use with care, and only when the system is safe or depressurized.
