Abstract
A test fixture for testing directional pilot valves as used in connection with turbine engine thrust reversers, and an associated method of use. In a particular embodiment, the test fixture has a base and at least one support mounted to the base to support the directional pilot valve. At least one fastener permits attachment of the directional pilot valve to the support. An adjustable actuator is also mounted to the base and is capable of stroking the directional pilot valve to simulate valve positions that may be encountered in operation of the valve. The adjustable actuator is also capable of maintaining a force, as set by a technician, against the directional pilot valve.
