A valve control is configured for use with control valves and other flow controls. The valve control leverages a simplified structure to avoid problems with manufacture and reduce costs. This structure includes a support unit that compresses parts of a valve housing together. Inside of the valve housing, the structure incorporates diaphragms that cause a pair of balanced valves to move in response to changes in pressure of fluid in a conduit. For industrial application, the valve control finds use to maintain pressure of natural gas in pipelines downstream from a control valve.

Valve control assembly

Control valve assembly

An actuator for use in a control valve assembly that has a structure amenable to manufacture. The actuator may comprise a housing comprising a plurality of walls secured to one another with fasteners to form an interior cavity, a torque hub disposed in the interior cavity, the torque hub comprising a torque body and a torque arm that are releasably engaged with one another via fasteners, each of the torque body and the torque arm having interfacing geometry that defines surfaces that engage with opposing surfaces on the other; and a load generator coupled with the torque hub.

Manufacture of actuators and control valve assemblies

A control assembly that is configured to operate large, heavy duty flow controls. The control assembly may include a main support and a thin plate disposed on the main support, the thin plate having four sides forming a mounting surface, the thin plate also having lateral slots that extend lengthwise in a first direction between two of the sides and are arranged so adjacent lateral slots are spaced apart from one another in a second direction perpendicular to the first direction.
