Explanation:

(....) The lifeguard, however, for any hydraulic actuator, is the overcenter valve. This motion controlling marvel is the successor of the counterbalance valve. The name counterbalance came from the counterbalancing weights used in the earlier machine tools to prevent the ball screw from coming under heavy load. These valves were designed in the early thirties by Harry Vickers’ team, who developed them as spool type valves and hence were not found to be zero leak.
