The Moog Servovalve Tester has been developed based on practical field
experience to provide a useful aid in commissioning, servicing and
troubleshooting control systems that use servovalves and pump stroker valves
with mechanical feedback. It is usually an advantage to separate the hydraulics
(servovalve) from the electronics.
To do this, simply remove the valve connection and connect the cable
(A48114-150) from the Moog Tester.The servovalve can then
be operated and checked completely independently of the system electronics.
In this way you can determine whether problems, such as null drift, unsuitable
oscillations or failure to achieve maximum speed, are hydraulic or electronic.
