EMERSON 239-634
AVENTICS/NUMATICS (239-634) ISO 1 Speed Control Assembly Unit
The ISO speed control kit mounts between the valve unit and any base, manifold, or RS regulator. The 3 and 5 ports of the unit contain needle valves which can be adjusted to throttle the flow of exhaust air out of the valve unit. Thus, the speeds of the two strokes of a cylinder piston can be adjusted independently on the same end of the speed control unit.
