SUNWARD Hydraulic Multi-channel Valve Test Bench  
Product name Hydraulic multi-channel valve test bench
The test bench was developed for the multi-channel valve used by1.8-47T excavators of SUNWARD. The test parameters through sensor, data acquisition and industrial PC realize static and dynamic data acquisition, processing, printing pressure loss curve, internal leakage curve, the relief valve pressure characteristic curve, reversing valves budge characteristic curve and relief valve transient response characteristic curve, the test reports and data management, etc.
Test projects ① The main valve setting pressure validation ② Commutation performance ③ Median leak test ④ Reversing a leak test ⑤ Withstand test
