Marshall Excelsior’s standard propane vent valve minimizes product loss whilst allowing you to safely bleed down connections and verify filling completion. When installed into the downstream auxiliary port on compatible Marshall Excelsior globe or angle valves, it provides an effective safety check and liquid-level detection method.

The brass valve features a Number 72 orifice size and 1/4-inch male national pipe thread connection. Opening it during filling lets you observe when liquid or vapour stops venting—a clear signal that it is safe to disconnect. ISO 9001 certified and made in the USA, it is backed by a 5-year limited warranty.
