Korean Patent Application Laid-Open No. 10-2015-0041476, which is a prior document, discloses a valve body manufactured by a casting process and a method of manufacturing the valve body. When the valve body is integrally manufactured by the casting process, there is a limitation in that it can be manufactured only with a material suitable for casting in relation to the purpose of the valve body, and there is a problem in that it is difficult to supply the material used for casting smoothly.

In addition, in consideration of the shape and size of the valve body, there is a problem in that the wooden mold and the mold must be separately manufactured and maintained according to the material, shape, and size. And, in order to change the shape of the valve, it is necessary to newly manufacture the entire mold. Therefore, as a large cost is incurred in manufacturing a mold, it is difficult to flexibly respond to customer requirements such as valve shape or specification change.

On the other hand, in the case of the conventional external pressure control type casting-molded valve (1'), the pressure gauge (3) and the auxiliary valve for pressure control (4) are installed in the piping line (2) as in FIGS. 1 (a) and (b). A structure in which the internal pressure of the external pressure control type casting molding valve (1') is regulated while the auxiliary valve (4) for pressure control and the external pressure control type casting molding valve (1') are connected through the connecting tube (5) However, this has disadvantages in that the configuration is complicated and manufacturing/assembly is cumbersome.
