Refer to print PR 23-1. The sequence of operations for this print is given below. Answer the questions following the sequence of operations. Sequence of operations onerator actuates the two push-button valves (1) and (2) until the weight starts to descend. lir passes through valves (1) and (2) to the time delay valve (3) and the pilot of valve (5). The four-way valve (5) is shifted, venting the head end of cylinder (4) and pressurizing the rod end. 4. The weight of the ram descends. The speed of descent is controlled by the exhaust control (7). The time delay valve (3) continues to time until the preset interval has passed. - The time delay valve (3) vents air pressure from the line between valve (2) and the pilot of valve (5). . With the pilot vented, the spring return of valve (5) shifts the valve to its normal position. O The rod end of cylinder (4) is vented and the head end is pressurized. 10. The weight ascends. 11. The speed of ascent is controlled by the exhaust control (6). Questions 8. What causes cylinder (4) to reverse? 9. What does the center line around valve (3) indicate? What component(s) are included? 10. Why is it not necessary to hold valves (1) and (2) down during the entire sequence?
