An electrohydrostatic actuator, comprising an actuator 150 for driving a component, a pump 112 configured to pump hydraulic fluid for operation of the actuator 150, and a control valve 200 for controlling passage of the hydraulic fluid between the actuator 150 and the pump 112, wherein the control valve 200 is movable between first and second positions. In the first position the control valve 200 is configured to convey hydraulic fluid from the pump 112 through the control valve 200 for operation of the actuator 150, and in the second position the control valve 200 is configured to fluidly disconnect the pump 112 and the actuator 150, and circulate hydraulic fluid arriving from the pump 112 back to the pump 112 via a first constriction within the control valve 200.
