What are the technical features of the comprehensive performance test bench for electronic expansion valves of industrial refrigeration equipment?

　　

This machine is designed based on JBT-10212 and JBT-10386, and is suitable for testing the flow characteristics, valve opening pulse, valve port leakage, maximum action pressure difference test, reverse valve opening pressure difference and other tests of electronic expansion valves. What are the technical features of the comprehensive performance test bench for electronic expansion valves of industrial refrigeration equipment? Let's see how Guangzhou Zhipinhui Electronic Technology introduces it.
