  • Publication number: 20240142008
    Abstract: An isolation valve includes an isolation valve body, a rotatable member and a connecting member. An outer cylinder section of the rotatable member has an end portion with an increased inner diameter towards an opening that an inner cylinder section of the isolation valve body penetrates through, and has an inwardly facing annular groove on its own inner peripheral surface between the end portion and a female thread of the rotatable member. The inner cylinder section has an outwardly facing annular groove facing the inwardly facing groove on its own outer peripheral surface. The connecting member has a cross section that is sized to fit within the outwardly facing groove. The connecting member is positioned astride the inwardly facing groove and the outwardly facing groove so as to prevent a relative movement between the inner cylinder section and the rotatable member in an axial direction along a rotation axis.
