CA 2058293
An improved combination steam and fuel oil supply and purge valve has a steam valve (42) and actuator member (48) which provides for a closed position, a purge operation with communication esta- blished between a steam supply line (26) and a discharge line (28) lead- ing to an oil burner, and a burner operation position wherein the actua- tor portion (48) of the member engages and opens a double acting oil supply and recirculation valve member (78) and thus establishes com- munication between an oil supply line (92) and an oil discharge line (40) to the burner. In its closed position the oil supply line and recircu- lation valve member (104) provides for communication between the oil supply line (92) and a recirculation line (110) which re-directs oil to a storage tank or the like for reheating and for maintenance of a desired viscosity during burner shutdown.
