It serves as a positive vapor recovery valve during loading and unloading, opening inward before the emergency valve through a sequential interlock system. This prevents surge pressure loss and ensures safe vapor venting. When air pressure is released, all connected valves close fully. Constructed from aluminum with stainless steel internals and PTFE seals, it meets DOT requirements for MC306 and DOT406 tankers. It is commonly replaced when the valve fails to open or seal properly, risking tank over‑pressure or loss of lading.
