Servo Hydraulic Valves are devices that detect oil flow in response to an electrical input signal
or instruction in order to regulate position, speed, pressure, or force in a machine or device
(often via a piston or cylinder). Servo proportional valves are closed-loop control devices that
come in single, two, or three stages. Servovalves and Servo-Proportional Valves are
electrohydraulically continuously functioning valves that transform a variable analog or digital
input signal into a stepless hydraulic output (flow or pressure). Proportional valves are
frequently used to regulate the pressure on a cylinder or hydraulic motor. They allow for
limitless roller placement and hence indefinitely variable flow volumes. The output flow or
pressure is proportionate to the change in inlet, thus three times the inlet generates three times
the output. Servo valves provide extremely high precision, repeatability, minimal hysteresis, and high frequency responsiveness. Servo valves are available in single-stage, two-stage, and
three-stage configurations. The servo valve's main operating concept is that variable low current
rather than variable low voltage is employed in system control. An amplifier receives the
control signal. The control signal to the amplifier is boosted even further, allowing the valve to
move to the proper position. The desired quantity of hydraulic power is therefore supplied to
the actuator. The position information of the actuator is translated into an electrical signal and
used asfeedback by a position sensor. This feedback is provided to the amplifier, which controls
the voltage produced to regulate the servo valve. The valve should respond to control signals
promptly and precisely, guaranteeing proper and efficient performance in your application.
