An 1807-1-1" NPT is a limiting orifice valve, specifically a 1-inch NPT (National Pipe Taper) valve. It's designed for accurately setting air/gas ratios on nozzle-mix burners, likely by controlling the flow of oxygen or other gases. The valve features an adjustable V-port plug that can be finely tuned using a screwdriver or Allen wrench, with counterclockwise rotation increasing flow. A cap conceals the adjustment mechanism to prevent tampering.
