Servo Hydraulic Actuators

Servo hydraulics actuators are solutions based on linear hydraulic actuators for reproducing the static and dynamic loading modes in testing of units and assemblies of various industries. Servo valve with feedback enables precision control of rod force and displacement. We use actuators with different characteristics for different types of tests
