Information

This example model shows a sequence of two operations: first a clamping and then a punching operation. A pilot-operated sequence valve is used to trigger the second operation once the clamping cylinder has moved far enough.

Fig. 1 shows how the punching cylinder starts to move when the clamping cylinder has reached a certain position. Fig. 2 shows how the pilot-operated sequence valve starts to move when the mechanically actuated valve has opened.
