Honeywell Eclipse ALO Adjustable Orifice Gas Flow Control Valves

Eclipse ALO series adjustable orifice valves are designed to maintain desired air/gas ratio by adjusting flow in gas lines feeding nozzle mix burners. They are available in ALO and ALO-R models.

ALO valves (left) come with a V-port that provides accurate gas flow adjustments. They can be adjusted by removing the cap and twisting the stem assembly clockwise to decrease the flow and counterclockwise to increase the flow.

ALO-R valves (right) are designed with the inlet and outlet ports at right angles to each other. This design feature allows them to be used in limited space installations or in place of a 90° elbow in a pipe line.
