Explanation of operation

Actuation of valve A (3P) extends the rod of cylinder D, which then retracts and stops. It is often used for reliable reciprocating operation.
[Detailed explanation of operations]
1. Pressing valve A supplies air to the pilot operator (34A) on the right portion of valve B (4PP), which then switches valve B.
2. As a result, the air previously filled in the rod side (left side) of the cylinder is exhausted from R2 of valve B. At the same time, air entering the cylinder head side (right side), extends the cylinder rod forward.
3. At this time, when the air passes through the speed controller (SCOF) to enter the cylinder, it opens the check valve inside the SCO-F and quickly fills in. For exhaust, however, the air is choked and the cylinder rod extends while decelerating.
4. When the cylinder rod extends to push against valve C, air is applied to the air pilot operator (34A) on the left portion of valve B, restoring valve B to its normal position, and then returnig the cylinder rod back.
