This month’s tip is about precise setting for vertical startups.
Air cylinders and other pneumatic devices are used throughout packaging machinery to pus, pull, hold, turn and more. Speed of an air cylinder is dependent on both pressure and flow. Most have a pressure gauge that allows accurate pressure setting. Most have needle valves to control flow but most of these needle valves have no position indication. This makes getting the setpoint correct a matter of guesswork.
In this month’s changeover video John Henry discusses the importance of positionable needle valves that can be set precisely by everyone ever time.
