Adjustable Flow Gas Burner Valve

THROTTLING SHUT-OFF VALVES
Our manually operated adjustable flow gas throttling shut-off valves combine the features of a main gas shutoff valve with that of an adjustable orifice. In the closed position, the valve shuts off all gas flow. In the open position, the flow rate of gas can be adjusted or “fine tuned” from full flow down to almost no flow for each application. To adjust the flow rate, the cap on top of the valve plug is removed and the position of the internal throttle is adjusted with a screwdriver. After the adjustment is complete, the cap is then replaced. The throttle has an anti-rotation feature that prevents inadvertent movement of the throttle after it has been adjusted. Maximum operating pressures range from 0.5 psig to 1.0 psig. Operating temperatures range from 32°F (0°C) to 350°F (176°C). Most models are design-certified by Canadian Standards Association (CSA) for use in the U.S. and Canada.
