The hydraulic valve cylinder comprehensive test-bed is a powerful and technically efficient test-bed. It uses domestic and foreign brand hydraulic components and electrical components, uses self-developed computer aided measurement and control software, uses electric proportional technology for remote control of test pressure, and uses electric proportional variable displacement pump for remote control of test flow; The test measuring point and measurement and control software have simple interface and powerful functions, including database storage, performance curve drawing, test report generation and printing, etc; It is equipped with overpressure alarm and automatic shutdown protection functions.



Scope of application:



Reversing valve - pressure test, steady pressure difference (flow characteristic test, leakage test);



Check valve - low opening pressure test and high pressure leakage test of check valve;



Relief valve - flow special test, flow step pressure response characteristic test, pressure relief and build-up characteristic test;



Pressure reducing valve - flow characteristic test, inlet pressure step pressure response characteristic test, outlet flow step pressure response characteristic test;



Hydraulic cylinder - startup pressure characteristic test, pressure withstand test and leakage test.
