Morrison Bros Co has released an air-actuated 3" emergency valve for the tank truck sector. The Fig 603 emergency valve is mounted on the underside of the tank on a petroleum tank truck or tanker.
This valve is available in both flanged and victaulic versions. It has a field-replaceable Bimba pnematic cylinder and a manual override to allow fuel to be released in case of an air system failure.
