Using Proportional Valves

All industrial maintenance personnel and technical staff have a need for information related to electro-proportional hydraulic valves and their circuit application. The use of proportional valves is virtually universal. Students will receive a thorough fundamental understanding of proportional valve types, how and why they are used and how they are controlled. The control signal stream for prop. valves from PLC to the valve control of the actuator will be thoroughly explained. Because proportional valve technology is the combined use of electronics and hydraulics, it is important for all maintenance trades to develop their knowledge. This training course covers relief valves, pressure reducing valves, direct operated directional control valves with and without spool position feedback, pilot operated directional control valves with and without spool position feedback, flow controls and high dynamic response directional control valves that are often referred to as “servo solenoid valves”. Valve control with “on-board electronics” and separately installed drive electronics will also be covered. It is important for the student to understand the difference between valve driver electronics and process controller electronics. This course also explains how electro-proportional valves are used to control various variable displacement pump operation.
