2. Electrohydraulic servo valve - Wikipedia

   en.wikipedia.org/wiki/Electrohydraulic_servo_valve

   A servo valve receives pressurized hydraulic fluid from a source, typically a hydraulic pump. It then transfers the fluid to a hydraulic cylinder in a closely controlled manner. Typically, the valve will move the spool proportionnaly to an electrical signal that it receives, indirectly controlling flow rate.

6. Control valve - Wikipedia

   en.wikipedia.org/wiki/Control_valve

   A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. [1] This enables the direct control of flow rate and the consequential control of process quantities such as pressure , temperature , and liquid level.

7. Flow control valve - Wikipedia

   en.wikipedia.org/wiki/Flow_control_valve

   Control valves can also work with hydraulic actuators (also known as hydraulic pilots). These types of valves are also known as automatic control valves. The hydraulic actuators respond to changes of pressure or flow and will open/close the valve. Automatic control valves do not require an external power source, meaning that the fluid pressure ...
