Packaging equipment makes extensive use of pneumatics technology because of its many benefits, and pneumatic cylinders prove especially versatile. They provide an economical and compact means of generating linear motion and also are clean, safe, and reliable.

Force applied by the cylinder is easily controlled by regulating pressure, and using an electronic regulator provides adjustable force on demand. Speed can be adjusted using simple needle valves or an electronic proportional valve that varies flow based on a control signal.
