  • Publication number: 20020063230
    Abstract: A manually-operated valve particularly for gas, with elements for limiting the opening stroke of an actuation handwheel, which comprises a valve body which internally forms a gas passage duct being controlled by a flow control element which can be actuated by a handwheel which can perform a translational motion by turning. Elements for limiting the opening stroke of the handwheel are further provided. The stroke limiting elements comprise a locking element which can move substantially at right angles to the axis of the rotation thread of the handwheel, the locking element engaging, at an opening stroke limit of the handwheel, an abutment for stopping the rotation of the handwheel.
