ABSTRACT:
A multiple rotary control valve of the pinch type for use in conjunction with a steam sterilizing apparatus. The valve comprises at least two side by side cams, each having cylindrical and flat portions for respectively pressing and releasing, in the proper sequence, flexible tubes conducting the fluids intervening in the sterilizing process. In a preferred embodiment, the cams rotate about an axis transverse to the tubes and are disposed between opposite pairs of tubes, and the tubes are trained and held in transversely aligned openings provided in detachable covers. A wear member is provided between the cams and the respective tubes.
