Flow Control Valves - 1/8” to 1/2” Port Sizes

Flow control valves are used to control air flow from air cylinders, thereby controlling the
speeds at which the pistons in the cylinders move. They allow free flow in one direction and
adjustable, precision controlled flow in the other direction. Adjustment in the X-type models
is by means of a screwdriver slot, and in the Y and Z-type models by a knurled knob.
