actuators Explanation: Could it be these? "The electro-hydraulic actuator for turbine valves essentially includes a control valve, a rapid action stop valve, a hydraulic supply and an oil supply unit. In order to create a hydraulic actuator for turbine valves which, on the one hand, satisfies the stringent requirements with regard to adjustment force and adjustment speed and, on the other hand, avoids the problems associated with the transmission of hydraulic energy, at least one adjustment valve and at least one rapid action stop valve are allocated per turbine inlet valve. The actuators of these two valves are of the same design and are mutually interchangeable and integrated into a compact actuator unit located on the valve housing. The actuators are connected in pairs to a hydraulic supply located immediately adjacent to the actuators. In addition, the actuators are controlled by a volumetrically controlled oil supply unit integrated with the hydraulic supply, this oil supply unit containing an adjustment pump for controlling the adjustment valve and an auxiliary pump for controlling the rapid action stop valve.

servo-loops Explanation: A servomechanism operates using feedback in a closed-loop configuration, often referred to as a servo-loop. You'll find a definition at the URL. A "lazo" is a loop. Reference: http://www.rane.com/par-s.html#servo_loop |
