とを特徴とするバルブ用ステム。In a valve stem that is equipped with a packing fitting groove provided in the part of the stem body that contacts the valve seat and a stem packing fitted in the same groove, the cross-sectional area of the packing fitting and the stem packing is made equal, When the valve is open, the top surface of the stem packing slightly protrudes from the opening surface of the packing fitting groove, and a gap is formed between the contact surface between the packing fitting and the system and the packing, and when the valve is closed, the above contact is made. A stem for a valve, characterized in that both sides of the packing-fitting cargo are in direct contact with the valve seat, and the packing-fitting groove and the stem packing have cross-sectional shapes that prevent the stem packing from coming off.
