A control system for controlling a gas generating system including at least two molecular sieve beds comprises a linear valve having a housing which includes an inlet connected to the gas generating system, a first port connected to a first of the at least two molecular sieve beds, a second port for exhaust, and a third port connected to a second of the at least two molecular sieve beds. Said inlet and said first, second and third parts are all in communication with a slide chamber having a slide block positioned in said slide chamber. The control system further comprises a push-pull device which is mounted to said housing for moving said slide block in a first direction and in a second direction, a sensor positioned at opposite ends of said slide chamber for sensing the position of said slide block in said slide chamber, and a controller for receiving information from said sensing device and for controlling said push-pull device. <IMAGE>
