<p>Actuators for use with fluid control devices having multiple fluid flow control members are disclosed. An apparatus includes a housing including a first chamber and a second chamber. The apparatus also includes a first actuator assembly at least partially positioned in the first chamber. The first actuator assembly includes a first stem to be coupled to a first flow control member of a valve. The first flow control member is to control fluid flow through a first flow aperture. The apparatus also includes a second actuator assembly at least partially positioned in the second chamber. The second actuator assembly includes a second stem to be coupled to a second flow control member of the valve. The second flow control member to control fluid flow through a second flow aperture, the first stem independently moveable relative to the second stem.</p> |
