Product Description:

Fill Limit Valve (threaded, National Pipe Thread Female)


  • Machined Aluminum, Blue Polymer Valve
  • Standard ullage depths range from 3/8" to 1-1/2"
  • FLVs are used to establish ullage (airspace) in the tank and help prevent overfilling.
  • Perko's FLVs connect to 5/8" hose. They are designed to vent to vented fuel fills and not directly to canisters.
  • Mounting options for tank mounted FLVs include flanged (for plastic tanks), threaded or welded (for metal tanks) and swivel (for both plastic and metal tanks).
  • Flanged valves match the SAE 5-bolt level sender flange. Gasket is not included.
  • Threaded valves mount with a 1" NPTF thread.
  • Swivel valves include valves, valve housing, o-ring, snap ring and tank insert.
  • Distant sensing (DFLV) versions are available for both plastic and metal tanks on a custom basis. Custom ullage set points are available. Contact the factory for details.
