FRANKLIN FUELING SYSTEMS 2 in. NPT Anti-Siphon Valve for Above Ground Tank 63630011

PREVENT FUEL FROM EXITING THE STORAGE TANK IN THE EVENT OF A BROKEN LINE OR LEAK EBW’s Anti Siphon Valves are recommended for all above ground storage applications to prevent fuel from exiting the storage tank in the event of a broken line or leak. The anti siphon valves shut off product flow when lines are broken, preventing fuel spillage and fire hazards. Each valve has an adjusting mechanism allowing for various liquid head pressure settings within the valve range. The adjusting mechanism is lockable after the preferred setting is made. EBW Anti Siphon Valves are set to maximum head pressure when shipped from the factory. The anti siphon valve also includes a pressure relief valve, eliminating thermal expansion of fluid in the lines.
