G040-119 Portable Servovalve Test Equipment

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.
