Modular-based test system for proportional valves

Based on the dynamic and static test performance requirements of a company for proportional valves, a hydraulic schematic and electrical control system for a proportional valve test bench was designed, on the basis of which a LabVIEW-based proportional valve test system was developed. The test and control software is based on a modular design, which allows the required functions to be handled in a modular way, greatly reducing the development cycle of the test software and facilitating later improvements and maintenance. The test results show that the test bench has high accuracy and stable performance, and can provide a reliable test basis and test means for the development and online inspection of proportional valves.
