Event Based, Cylinders Extend in Succession.
(Poppet Valves Shown)
Cylinder number 2 extends only after cylinder number 1 has
reached a predetermined stroke (limit valve). Cylinders will retract
almost simultaneously when the manual valve
is released.
Event Based, Cylinders Extend, Retract
Automatically.
(Spool Valves Shown)
This circuit, when manually initiated, will cause the two cylinders to
extend in sequence, then retract automatically. The manual valve
will be returned to its original position in the process.
