It is designed as a pilot control device, meaning it uses an electrical switch to send a small air signal to operate larger components like dump valves or other pilot-operated accessories in an air system. It is commonly used to control air ride suspension dumps or other basic pneumatic functions. It is self-relieving, so it vents its output port when de-energized, but it is not intended to be used directly as a primary dump valve.
