AST Overfill Prevention Valve – AA Series (3")

The 9095AA valve is installed at the fill port of a storage tank. Designed for use in pressurized fill systems and requires a tight fill connection. The valve installs in a standard 6” NPT male riser connection and can be set to the desired 90% or 95% shut off level by using standard length pipe nipples.
When installed to the manufacturer’s specifications, the overfill prevention valve can help eliminate hazardous spills. A mechanical test mechanism is available and sold separately.  The test mechanism allows a technician to pull the test line at any time during the filling process to actuate the float and stop the fill.  This allows a technician to verify the valve is working properly.
