1955 Tanker Truck Valve
PATENT PENDING
The Wager 1955 Tanker Truck Valve is a combination of a vent check valve, and a pressure relief valve all rolled into one self contained unit.

The Valve is designed to prevent spillage from tanker trucks during turns or braking, while allowing for adequate venting so that a vacuum

cannot be created while in the dumping mode. A spring mounted pressure relief cap assures safety should the tank be over-filled.
.

This valve was designed by a firefighter to be:


• Affordable
• Easy to install or retrofit
• Maintenance free operation
• For use with both flat or elliptical tanks
• Fully operational in all climates
