ABSTRACT:
A selector valve system has been invented for selectively operating a motor for selectively actuating a main line valve on a pipeline, gas flowing through the pipeline, the system having, in one aspect, a body, a first poppet valve mounted on a first channel through the body, a second poppet valve mounted in a second channel through the body, a first limit valve for controlling flow of a portion of the gas to the first poppet valve so that upon such gas flowing to the first poppet valve the first poppet valve is actuated to permit gas flow to the motor to open the main line valve, and a second limit valve for controlling flow of a portion of the gas to the second poppet valve so that upon such gas flowing to the second poppet valve the second poppet valve is actuated to permit gas flow to the motor to close the main line valve. In one aspect the poppet valves are O-ring-saving cartridge valves.
