Harmon Racing Cells Fuel Discriminator and Rollover Valve AN -10 ORB Female Inlet/Outlet 2-1/4" Body

Discriminator valves prevent fuel from traveling up the vent line during filling when the tank is full. Utilizing a float, the valve shuts off air flow when fuel enters the chamber. The valve also operates independently and will close/shut off if overturned regardless if there is fuel in the chamber. Because of its ability to prevent fuel from traveling up the vent line and out the vehicle these have become popular on vehicles utilizing dry break and pressurized fill systems.

Note: If you're rebuilding Harmon's #10 ORB discriminator valve, if you have the first generation valve (picture shown below and usually blue) with the metal balls, you'll use the HRBK0010 rebuild kit part number. If you have the second generation valve with the plastic looking balls, you'll use the HRBK100V that Harmon uses on all their other discriminator valves.
