Short Description:

The Betts 6496ALV Normal Vent is a dual purpose, pressure and vacuum vent for DOT406 tank trailers. It is made from aluminum, has 1 5/8-12 UN mounting threads, and has a Viton seal. This vent normalizes internal tank vacuum and pressure through the use of a unique weighted roll-over block, which increases the set pressure of the vent in a roll over situation but does not act as a shutoff device, allowing the vent to maintain its primary function as a relief device in all situations. The vent is flow tested and marked in accordance with DOT requirements.
