Introduction 



1) Using microcomputer controlled high precision electro-hydraulic servo valve to drive precise hydraulic cylinder and can realize constant speed control to test force, displacement, deformation, etc. and so that to make tensile, compression, bending tests. 



2) Independent hydraulic servo loading system, using high precision broadband electro-hydraulic servo valve to ensure system high precision, 



3) Limit position protection, over current protection, overload protection
