Designed for use in pressurized fill systems and requires a tight fill connection. The unique design can be used on low profile storage tanks requiring a high shut-off point. 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.
Features
- Shut-off level can be set to 1 1/4” from the top of the tank
- Top fill, remote fill and dry disconnect connections available
- Can be retrofitted to tanks with a 4” opening
- Attach 2” model 419 drop tube with included drop tube adaptor
- The shut-off level can be set by using standard length pipe nipples and utilizing 5” of adjustability integrated into the float assembly
