ABSTRACT:
A method and apparatus for maintaining the flow rate of one or more secondary fluids proportional to the flow rate of a primary fluid is disclosed. A valve is located in a primary fluid line and a valve is located in a secondary fluid line. An actuator drives linkage to operate the valves in approximate proportion to one another. A sensor senses the fluid pressure in the primary line and the sensed pressure is delivered to each regulator in the secondary lines. The regulators adjust the static pressures of the secondary fluids downstream of the valves to the desired proportional level.
