It controls the flow of air from the trailer's supply to the lock pin retraction mechanism, allowing the driver to quickly reposition the trailer axles. You would replace this valve if the slider pins fail to retract or release properly due to air leaks or internal valve failure. Note that this valve is part of a larger system that requires a pressure protection valve plumbed directly to the air tank to comply with federal safety regulations.
