Proportional and Servo Valves
Hydraulic Servos
Dynamic Response for Intelligent Hydraulic Systems

Used in closed loop control system applications, electrohydraulic servo valves have the highest dynamic response for intelligent hydraulics systems. With the appropriate system feedback and controller design, Rexroth hydraulic servo valves are unsurpassed in controlling pressure, flow, or position. Servo valves are appropriate for systems with one or more of the following characteristics: high load stiffness (static or dynamic); high accuracy and stability; precise positioning; fine control of velocity and acceleration control.
