Abstract: An in-line serviceable cutoff valve with excess flow capability includes a valve body and a separable cover. Internal valve components are accessible for service or replacement when the separable cover is removed from the valve body. The internal valve components may optionally be attached to the separable cover so that the separable cover and the internal valve components may be removed as a single assembly.

Abstract: A valve including a control assembly that is configured to control fluid flow through the valve, The control assembly includes a driving element and a valve member. The driving element is rotatable about an axis between a first operating state in which the driving element maintains contact between the valve member and a valve seat and a second operating state in which the driving element does not maintain contact between the valve member and the valve seat. The valve member is rotatable about the axis independent of the driving element when the driving element is in the second operating state.

Abstract: An actuator assembly for use with a shut-off valve in a transport or storage system. The assembly is configured to be operatively coupled to a stem of the valve for controlling fluid flow therethrough. The assembly includes a mounting bracket coupled to the bonnet, a mounting sleeve coupled to the stem and movable relative to the mounting bracket, and an actuator having a body and an inlet formed in the body. The body is defined by a first body portion coupled to the mounting bracket and a second body portion coupled to the mounting sleeve and movable relative to the first body portion to expand or contract the body. The inlet is adapted to receive pressurized fluid; the body expands or contracts responsive to the pressurized fluid, and responsive to the expansion or contraction of the body, the mounting sleeve moves relative to the mounting bracket, thereby moving the stem.
Abstract translation: 用于运输或存储系统中的截止阀的致动器组件。 组件被配置为可操作地联接到阀杆，用于控制流过其中的流体流动。 组件包括联接到发动机罩的安装支架，联接到杆并可相对于安装支架移动的安装套筒，以及具有形成在主体中的主体和入口的致动器。 主体由联接到安装支架的第一主体部分和联接到安装套筒的第二主体部分限定，并且可相对于第一主体部分移动以使主体膨胀或收缩。 入口适于接收加压流体; 主体响应于加压流体而膨胀或收缩，并且响应于主体的膨胀或收缩，安装套筒相对于安装支架移动，从而移动阀杆。
