ABSTRACT:
A slide spool valve has a valve body formed by synthetic resin injection molding. The valve body includes a bore and an insert integrally coupled with the bore. The insert has a hollow portion penetrated by a port, the hollow portion being connected to the bore and having the same diameter as the bore and penetrated by one of ports. A valve room having a large diameter extends from an inner circumferential surface of the hollow portion to the penetrating portion of the port. The insert is manufactured by die casting and fixed in a metallic pattern of the valve body, so that it is integrally coupled with the valve body by insertion molding.
