When Experience Matters!


Morrison Bros 9095AA 3″ AST Overfill Prevention Valve


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. Standard Features
  •  Top fill, remote fill and dry disconnect connections available
  • Attach 3 Inch model 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
