1. A control valve for a hydraulic actuator, comprising:
- a valve body defining a translation axis;
a spool disposed within the valve body and movable along the translation axis; and
a flange connected to the spool and having an aperture is disposed externally of the valve body, wherein the flange is fixed relative to the spool to removably fix the spool to a spool of a redundant control valve that is independently connected to a multi-stage hydraulic actuator.

Abstract
A control valve for a multi-stage hydraulic actuator includes a valve body defining a translation axis, a spool disposed within the valve body and movable along the translation axis, and a flange. The flange is fixed relative to the spool and has an aperture disposed externally of the valve body to removably fix the spool to a spool of a redundant control valve independently connected to the multi-stage hydraulic actuator for mitigating force fights between actuators coupled to the control valve.
