Claim 7:
8. The method of claim 7, further comprising:
displacing, with hydraulic fluid pressure from a fluid, the spring-biased spool of a second stage of the servo valve;
transitioning, by the displacing, the spring-biased spool from an active state, where the servo valve is in fluid communication with a pressure source of at least one of the primary stages, and a bypass state, where the servo valve is isolated from the pressure source;
moving the first actuator piston when the servo valve is in the bypass state;
actuating, in response to movement of the first actuator piston when the servo valve is in the bypass state, a pilot valve in fluid communication with the second fluid chamber of the one or more actuator housings and comprising a stem configured to project into an interior bore of a frame of the bypass valve; and
bearing, based on the actuating, the stem against the spring-biased spool.
