A compact, axially aligned brushless servo motor actuation unit configured to manipulate a choke valve to control the pressure within a borehole during managed pressure drilling. The actuation unit including a brushless servo, a gear reduction assembly and a planetary roller actuator substantially aligned along a longitudinal axis and housed within a tubular housing, the gear reduction assembly defining a hollow core sized to enable a portion of a roller screw of the planetary roller actuator to pass therethrough for the purpose of reducing the overall length of the actuation unit along the longitudinal axis.

Actuator for choke valve

Devices and methods for operating a linear actuator, optionally for use in controlling a choke valve as part of a managed pressure drilling operation. Such a device may include a motor, a transmission, a linear actuator and an override mechanism selectively engageable with the transmission to enable operation of the linear actuator independently of the motor.

The present disclosure relates to a manual override tool for an electric actuator. The manual override tool includes an accessible first end, a shaft operably connected with the first end and is movable in a linear direction and is rotatable, and a plurality of gear teeth on the shaft. The accessible first end is used to engage and disengage the plurality of gear teeth with a plurality of notches provided on an interior rotor of the electric actuator, such that the accessible first end may be used to manually operate the electric actuator.
