A first transfer path and a second transfer path are formed in the upper part of the main body so as to be able to flow the fluid to the hydraulic line, the discharge line, the first transfer line, and the second transfer line, A flow rate valve for adjusting the amount of fluid at the upper end of the main body so as to allow the fluid to flow through the hydraulic pressure, the discharge path, the first transfer path, and the second transfer path; a pressure reducing valve for adjusting the fluid pressure; The valve is laminated and connected so as to be connected as one pipe.
The flow valve, the pressure reducing valve, and the directional valve may be formed for each of the compartments including the hydraulic line, the discharge line, the first transfer line, and the second transfer line. Grooves are further formed and a cover for preventing fluid flow can be further formed when the hydraulic line, the discharge line, the first and second transfer lines, the pressure line, the shutoff line, and the additional line are not used.
The main body has a structure in which a plurality of main bodies can be connected to the side surface of the main body in such a manner that the hydraulic line and the discharge line penetrate through the main body and the first and second transfer lines are formed on both sides of the main body, will be.
The present invention is capable of controlling the hydraulic pressure and flow rate through a valve that can move fluid through a pipeline formed in a hydraulic direction switching block and stacked on the top of a flow path plate, And is easy to deform.
Further, it is an object of the present invention that the mounting space can be reduced and the assembling work can be performed easily and quickly.
Further, troubles caused by piping such as leakage, vibration and noise are generated little and are installed in a laminated form, so that maintenance and inspection are simple.
