The oscillating valve generates oscillatory actions such as vibrations, tapping or dipping in connection with double acting cylinders. If input 1 is supplied with compressed air, the compressed air is alternately applied to outlets 4 and 2. The valve switches over into a time-pulse (Forward and return strokes) that can be adjusted using 2 adjustment screws. The speed of the controlled cylinder must be adjusted separately using the bi-directional flow control valves.
