This article explores the benefits of replacing legacy servo valves on extrusion presses with proportional control valves. Engineered to easily fit into existing extrusion press hydraulic systems, these proportional valves are rugged and tolerant of contamination, and provide equal or better dynamic hydraulic flow control. The article discusses how proportional control valves can eliminate persistent operational problems, are more reliable, and can improve how press operators manage extrusion performance.
