Circuits That Run Indefinitely

Look at the following pneumatic circuit. In this circuit, we have a configuration of 4 different DCV. These 4 valves are configured in a way that when the manual DCV valve is actuated, the cylinder will run indefinitely as long as there is a supply of air. This circuit would be considered a reciprocating circuit, because it can run indefinitely. This type of circuit is used when we want to automate a cylinder to do work. An operator only needs to activate the cylinder once for it run.

Watch the following video:

Here is another video that shows the circuit that you will build in operation mode.

As mentioned above, in order to make this reciprocating pneumatic system work, we use 4 DCV. These are the valves that we use:

- One 5-port (4-Way), 2-position, Detented, Toggle-Style Actuator
- One 5-Port (4-Way), 2-Position, Pilot-Operated
- Two 3-Port (2-Way), 2-Position, Roller Lever

Watch the video in the following lab to learn how to set up and operate the lab.
