In spite of simple construction having no control valves, high accuracy positioning and pressure controls are possible.
Energy saving system provides necessary flow and pressure when necessary, free from pressure loss which would be generated by control valves.
Because of small heat generation by pressure loss and therefore, no cooling system needed, the tank capacity can be minimized.
Compared with the bell screw loaded by the point contact, the hydraulic cylinder loaded by the face pressure is longer in life time and is capable of maintaining its accuracy for a long time.
