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: 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.
