<p>The present invention relates to an apparatus for controlling flow, which is equipped in an intercepting facility, comprising: a valve main body wherein a flow path is formed in the lower part of a body; a gate combined with the valve main body to open and close the flow path; an air cylinder mounted on the valve main body and combined with the gate to lift the gate by compressed air; a weight installed in the valve main body and connected to the gate to offset vertical load due to weight of the gate; and a remote driving part installed outside the valve main body and having a cable winding part to remotely drive, and to open and close the gate. The present invention has effects of minimizing capacity of an air cylinder; smoothly opening and closing a gate manually at a predetermined distance away; precisely controlling the opening amount of an apparatus for controlling flow by checking the opening and closing amount of a gate when the gate is manually operated; reducing opening and closing load of a gate by removing negative pressure applied to the gate; and preventing opening and closing defects of a gate as a gap between a gate and a valve main body is not filled with foreign substances.</p> |
