At the upper end of the stand 10, a hydraulic block 20 is formed. The hydraulic block 20 is provided at the upper end of the stand 10 and has a through-hole formed therein. That is, the hydraulic fluid supplied to the valve driver for performing the opening and closing operation of the valve is passed through the through-hole in the hydraulic block 20. [

A hydraulic pump (30) is formed at one side of the stand (10). The hydraulic pump 30 is provided at one side of the hydraulic block 20 and serves to generate a pressure in the hydraulic fluid delivered to the hydraulic block 20.

That is, the hydraulic pressure is generated in the hydraulic oil delivered to the inside of the hydraulic block 20 by the upward and downward movement of the lever 32 formed at the upper end of the hydraulic pump 30, Flows through the flow path (50) or the second flow path (60) and operates the valve driver installed at the upper end of the valve located at a remote location to open and close the valve.

This allows the hydraulic pressure generated by the hydraulic pump 30 to be transmitted to the hydraulic block 20.

An open / close valve (40) is formed at one side of the hydraulic block (20). The on / off valve 40 is formed on one side of the hydraulic block 20 so as to open and close the flow of hydraulic oil in the hydraulic block 20.

That is, the on-off valve 40 serves to flow the hydraulic oil in the hydraulic block 20 with the valve located at a long distance.

More specifically, the on-off valve 40, which is constituted by a pair, is configured to be able to supply hydraulic oil to the valve actuator of the valve located at a remote position, and a hydraulic oil for closing. That is, the first and second flow paths 50 and 60, which will be described below, are respectively coupled to the on-off valves 40 to selectively supply the operating fluid to the valve actuators located remotely.

On the other hand, when the valve is closed, the directional control valve 70 is switched to the other direction to enable the flow of the operating fluid through the second flow path 60. At this time, The working fluid passing through the second flow path 60 operates the valve driver to close the valve.

This serves to enable the opening and closing operation of the valve located at a remote location to be operated by the direction control valve (70).

At the upper end of the hydraulic block 20, a plurality of flow meters 80 are further provided.

The flow meter 80 is provided at the upper end of the hydraulic block 20 and detects the pressure and direction of the hydraulic fluid flowing through the first flow path 50 or the second flow path 60.
