A normal vent designed for use on MC306 & DOT406 cargo tanks. Model 6496 has a pressure setting of “no less than 1 PSIG” and a vacuum setting “no more than 6 ounces” which allows efficient recovery of vapors during closed system loading and off-loading. Unique roll over protection retains product at any attitude of rollover. Vent is flow tested and marked.
Note: While normal vents provide limited vapor venting during loading/unloading, it is recommended that positive vapor valves (typically air operated) be provided when loading/unloading with the manhole closed. If positive vapor valves are not used, insure normal vent is functioning properly or open manhole cover before beginning loading/unloading. Failure to do so may result in head reversals or other tank failure.
