ABSTRACT:
A control arrangement for a gas-fired system. Three diaphragm-operated valves are in series providing a stage operation. The valves are pilot controlled. A booster pump is provided for cooperation with the pilot valves to boost the line pressure to the first of the valves, the boosted pressure being sufficient to operate the diaphragm valves, and the boosted pressure being controlled by the pilot valves. The booster pump operates only when needed. Diaphragm-operated pilot valves means are provided which operate two separate pilot valves which control the pressure on the opposite sides of the diaphragm of the diaphragm valves. The system provides stage operation, the stages including a first stage which is closing of a vent valve connected between diaphragm control valves, opening of a first diaphragm valve, and a third stage which is a controlled slow opening of the second diaphragm control valve. The first diaphragm valve is both a control valve and a pressure regulator.
