This circuit utilizes the flow divider specialized for synchronization.

In this circuit, the flow control valve controls fluid flowing in and out of the cylinders. Generally, a high accuracy valve is employed.

This circuit realizes a synchronized motion by mechanically combined cylinder rods. In the following figure, the relationship between the two main cylinders and two other…

By using a pump and an electric motor specialized for filtration, this circuit filters contaminants even when the main hydraulic pump is not turned on.…

This circuit filters a small amount of the by-passed outlet flow from the pump (about 1 to 2 L/min (0.26~0.53 U.S.GPM)).

This circuit filters working fluid going back to the reservoir. The filtration rate is approximately 10 //m to 20 ^m.

This circuit protects the directional and other control valves in the line. Its filtration rate ranges from about 10^m (solenoid/proportional valve) to 3 ^m (servo…

This circuit’s objective is to protect the hydraulic pump. This circuit has two types: in one type, a filter is set inside a reservoir on…

In this circuit, the subsidiary cylinders and the pre-fill valve help the main cylinder achieve pumping function. This circuit drastically reduces the pump-output volume required…

When the cylinder is pushed forward, working fluid discharged from the cylinder head is added back to the cylinder cap because of the difference in…
