Deck stand, a hydraulic system, may be combined with electric components and generate hydraulic pressure by the rotating movement of cam regardless of electric components. The direction of hydraulic pressure is subject to the rotating movement of cam, transmitted to each port.
Hydraulic pressure is generated by the proportional movement of a piston according to the rotating height of a cam. The cam-rotating type features the use of external gears for good durability.
Also, it has a filter in hydraulic ports to prevent the malfunction of blocks by foreign substance.
It is applied to the operation of marine and land valves.
