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.
For use on clean liquids only.
Standard Features
Top fill, remote fill and dry disconnect connections available
Attach 3” Morrison 419 drop tube with the included drop tube adaptor
Adjustable float (1 1/2”)—for setting the precise shut off height
Integrated bleed hole prevents siphoning through the valve
Immediate and cushioned shutoff eliminates line shock
Full flow up to within seconds of valve closure
Integral anti-siphon function
Once closed, the integrated bleed hole featured allows less than 2% of the maximum flow to relieve fill line pressure allowing the fill nozzle to be removed without spilling product
Valve operates on simple mechanics with minimal moving parts. Shutoff is activated by basic hydraulic principles with not springs, levers of complicated sequence leading to valve closure
Typical flow rate is 550 GPM at 10 PSI pressure drop
5 PSI minimum flow requirements. The valve will not work in gravity filling applications
