PURPOSE: An integration type case for protecting the water supply valve and a method for manufacturing the same are provided to form parts integrally by casting for preventing the permeation of water via a main body and simplify the installation work, thereby protecting a valve safely and promoting the speedy opening or closing manipulation of the valve. CONSTITUTION: An integration type case for protecting the water supply valve includes a cylindrical main body(11), upper and lower flanges(12,13) integrated with the main body at upper and lower parts for connecting a manhole body with a floor plate element, a fixing flange tube(14) integrated at a side of the main body, protruded inwardly and outwardly, formed with connection flanges inside for connecting a valve, and connected with a water supply pipe outside, and a fixing connection tube(15) integrated at the other side of the main body, protruded inwardly and outwardly, retractively inserted with a movable flange tube connected to the valve at the opposite side of the fixing flange tube and connected with a water supply pipe outside.
