SERVO VALVE TEST BENCH
Servo Valve Test Bench
This Servo Valve Test Stand is specifically developed for the maintenance and testing of servo valves and proportional valves. Utilizing advanced computer technology, it is designed to measure four-way plate-mounted flow control valves. Users receive intuitive operational guidance via on-screen graphics. Test results can be saved directly to the computer and printed as compre
Pressure Gain Curve
Displays the pressure gain of the servo valve; performance data near the null point is primarily used when required.
Internal Leakage Test
This schematic illustrates the relationship between the servo valve's leakage flow and the input signal. The increase in leakage volume observed near the null point reflects the actual leakage condition of the valve spool.
Signal-to-Flow Test
This schematic illustrates the flow test results. These curves are used to identify common servo valve faults, such as non-linearity, contamination, or abnormal wear of the feedback ball.
Signal-to-Spool Feedback Test
This schematic illustrates the spool position of valves equipped with electrical feedback. It is a critical diagnostic tool. For larger servo or proportional valves, the spool position is typically controlled via a closed-loop positioning mode. The output signal from the integrated position sensor is provided through the valve connector.
Since high-flow valves often inv
Step Response Test
The step response is utilized to evaluate the opening and closing dynamics (switching speeds) of the servo valve.
