Specifically designed for use with oil burners applied to glass furnaces with reversal systems. At the completion of the firing cycle, this valve will, (a) shut-off the oil flow to the burner and, (b) extract or withdraw the oil in the burner back into the valve oil storage chamber. This prevents the burner from after-burning, and dripping or cooking at the end of reversal, thus protecting the melt and the furnace. Use one valve per burner for best results.
