A control assembly can be configured for use with a pressure regulator having a valve body defining a fluid flow path. The control assembly can include a control member, a stem, and a lever, and can be disposed within the pressure regulator to selectively control fluid flow. The control assembly can include a primary control member and a secondary control member, or a mechanical stop that can operate to restrict flow along the fluid flow path, including when the stem disconnects from the lever.

Flow limiter for regulators

A cage for a control valve trim assembly includes a cage body having an opening at one end and a wall extending from the opening, a plurality of cage openings disposed in the wall, and a pressure relief mechanism disposed in the cage wall.

Valve sound reducing trim assembly with pressure relief mechanism

A control assembly for converting a 'fail-close' regulator to a 'fail-open' regulator, or vice versa, without having to modify or reconfigure a casing of the regulator includes a control member, a central rod, and a spring disposed between first and second spring seats. A regulator including the control assembly includes a valve body and an actuator casing, the valve body defining a fluid flow-path. The control member is slidably disposed within the actuator casing and adapted for displacement relative to the valve body for controlling the flow of fluid through the flow-path. The spring and spring seats are disposed about the central rod, such that the spring biases the control member into a predetermined position relative to the regulator casing.

Positioning device for pressure regulator

A control device includes a valve body, a seat ring, and an actuator. The valve body defines a flow-path for a fluid. The seat ring is disposed within the flow-path. The actuator is coupled to the valve body and includes a control member. The control member is adapted for displacement relative to the seat ring for regulating a flow of the fluid through the flow-path. The control member includes a sealing disk adapted to sealingly engage the seat ring and close the flow-path. The seat ring includes a plurality of orifices disposed within the flow-path such that the seat ring prevents at least a portion of the flow of the fluid from substantially perpendicularly impacting the sealing disk.
