ABSTRACT:
Mechanism for controlling flow of cleaning fluids under pressure to a discharge nozzle of cleaning apparatus using steam or hot water for industrial cleaning purposes. A control valve for controlling flow of the cleaning fluid is operated by other fluid introduced thereto by an automatically closing manually opened valve. The control valve is arranged to close gradually when the manually opened valve is permitted to close, to prevent shock loads in the fluid system.
