It is a normally closed, pilot-operated valve that releases air pressure to deflate trailer suspension air bags, allowing the vehicle to lower. This valve is replaced when the dump function fails to engage or when air leaks develop, common issues from internal wear or contamination. It serves as a critical component for automatic dump operation on air‑ride trailer suspensions.
