- Figure shows a simple pneumatic circuit diagram using two cylinders A and B, -both cylinders are single acting actuated sequencially by a roller operated 3/2 directional control valve.
- With the actuation of the detented D.C. valve 2.2, the line is energised.
- As valve 1.1 is actuated by a manual lever, cylinder A adavances and actuates valve 1.2 which sends am impulse to the pilot operated valve 2.1 and cylinder B advances.
- Cylinder A returns when lever is reset. Cylinder B then retracts asthe valve 1.2 is released.
