1/2" to 2" NPT threaded and 2.5" to 4" ANSI 150lbs flanged orifice valves

The VLO orifice valves are designed for a very accurate control of gas flow for the nozzle mix burners, especially in a mutiple burners design for a perfect adjustment of each individual burner. Gas flow is set through a proportional V shaped series of ports. Threaded versions have two different inlet ports, an axial one and a 90 degree one. They are shipped from DUNGS with the axial set-up but can be modified by the customer without further parts. Flanged versions only have an axial inlet port. The VLO valves are not designed to be used as manual blocking valves, but as manual flow control valves.
