Course HYi-302-Gauge: HYi-302 Proportional Control Technology (formerly PCT)
Description Electro-proportional hydraulic valves have become evermore present in most hydraulic powered and controlled machines and processes. This course offering will bridge the gap between conventional valve technologies and so called continuous control valves through understanding the operation of the valve and control. For this purpose there will be ample time devoted to the actual interconnection and operation of valves and their associated control electronics. Students will configure the electronic interface and place the valve in working circuits to observe the operation and tune the control. Through this hands-on approach, students will develop their setup and troubleshooting skills. This 5 day training course is also a proper starting point for plant engineering personnel prior to our advanced HYi-303 Proportional Circuit Design course.
Target Audience Advanced technicians, electrical and controls personnel and engineers gain a comprehensive understanding of proportional control valves and circuits
Length 4.5 days
Cost 2500 CAD
