Selecting an Aventics pneumatic valve for equipment
 

One of the pneumatic valves on our production line has recently started malfunctioning. Sometimes it activates with a slight delay, although we never had this problem before. The equipment is used every day, so I decided to replace the valve if it is indeed the source of the problem. The old valve already shows noticeable signs of wear, but I’m not sure which model to choose as a replacement. How do you usually select an Aventics valve for a specific piece of equipment?
