Air cylinders are pneumatic linear actuators that are driven by a pressure differential in the cylinder's chambers. They may be single-acting (with a spring return) or double-acting.
Air valves allow metered fluid flow in one or both directions. They are used in pneumatic circuits to regulate the rate of activation or exhaust of cylinders and other pneumatic devices.
Filter, regulator, lubricator (FRL) assemblies are pre-packaged or modular assemblies of common configurations of air filters, regulators, lubricators, and gauges.
