Claims

[Scope of Claim for Utility Model Registration] (1) A valve box body having an inlet side opening and an outlet side opening and cast using a mold, a valve body housed in the valve body body, and a valve body housed in the valve body body. and an inlet port section and an outlet port section that are formed separately and communicate with the inlet side opening and the outlet side opening, respectively, and the inlet side opening and the outlet side opening are arranged along the operating direction of the valve body. The dimension in the operating direction is larger than the dimension in the vertical direction perpendicular to the operating direction, and each port portion is integrally provided with a flange for fixed connection to the valve body body with a sealing member interposed therebetween. A poppet-shaped valve characterized by: (2) A valve body body having an inlet side opening and an outlet side opening and cast using a mold, a valve body accommodated in the valve body body, and a valve body formed separately from the valve body body and having the above-mentioned entry. An inlet port portion and an outlet port portion are provided which communicate with the side opening and the outlet opening, respectively, and each port portion is integrally provided with a flange for fixed connection to the valve body body with a sealing member interposed therebetween. The opening of the flange portion on the side facing the inlet opening and the outlet opening of each of the port portions has a dimension along the operating direction of the valve body in a vertical direction perpendicular to the operating direction. A poppet-shaped valve characterized by its larger size. (3) The sealing member is fitted into an annular groove surrounding each of the openings, the dimension of which is larger in the operating direction than the dimension in the vertical direction perpendicular to the operating direction.
