How to test the performance of automotive electronic expansion valves, solenoid valves, and four-way valves on a performance test bench

　　
This device is suitable for performance testing of electronic expansion valves, solenoid valves, and four-way valves. So, how do you test the performance of automotive electronic expansion valves, solenoid valves, and four-way valves? Let's see how Guangzhou Zhipinhui Electronic Technology introduces it.

1. Number of Workstations: 1, for sample replacement (electronic expansion valve, solenoid valve, four-way valve)

2. Power Supply: AC 220V/50Hz

3. Test Medium: Air or Nitrogen

4. Air Source Pressure: High-pressure air above 6 MPa

5. Flowmeter Performance: Response time: 10ms, accuracy: ±0.8% of reading ±0.2%FS

Flowmeter range: 0-250 L/min, leak test flowmeter range: 0-5 L/min, high-quality international brand, resolution: 0.01 L/min

6. Pressure Reducing Valve Performance: R11 series high-pressure pressure reducing valve, inlet pressure: 15 MPa, outlet pressure: 4 MPa. Low-pressure pressure reducing valve: Japanese high-precision servo pressure regulating valve, sensitivity: 0.2% F.S., repeatability: within ±0.5% F.S.

Air Flow Test: 0.1 MPa compressed air
