Sequencing Circuit with Rotary Actuators

This example shows a sequence circuit that is based on four check valves installed in both pressure and return lines of the second rotary actuator. The cracking pressure of all the valves is set higher than any load pressure of the first actuator, but lower than pressure that develops in its chambers at the end of the stroke when actuator hits the stop. As a result, the second actuator starts moving only after the first one completes its stroke.
