G040-124-002 Direct Drive Valve (DDV) Tester

The Moog G040-124-002 Direct Drive Valve (DDV) Tester tests a DDV, without the need for electrical power or hydraulic supply. Internal rechargeable batteries eliminate the need for external electrical power by powering the Tester as well as the valve.

Testing is simple and straightforward. Plug the Tester’s connector into the valve, rotate the command potentiometer and observe the spool LED display following the command. A hydraulic supply is not necessary because the force to position the spool is generated electrically by the valve’s linear force motor.

A measurement of the valve’s operation can be made with a digital multimeter on the command and spool test points.
