A controller is configured to operate a flow control. These configurations may operate an actuator that is part of an industrial valve. In one implementation, the controller may include a solenoid valve that couples with the actuator. The controller may utilize feedback from the valve, for example, sensor data, to identify changes that it needs to make to the solenoid valve. These changes can direct flow to different sides of the actuator.

Controlling an actuator on a valve

A component for a ball valve that is configured to reduce noise. The component or 'shoe' can install into the valve body, for example, on a downstream side of a throttling ball. In one implementation, the embodiments comprise an annular ring with an inner surface and an outer surface. The inner surface is cupped to receive a portion of the throttling ball. The outer surface may have a stepped profile with portions of the annular ring that have concentrically-decreasing diameter. This stepped profile sits in a corresponding recess in the valve body. Welds can be used to secure the shoe in place in lieu of fasteners, like bolts or screws.

Reducing noise in ball valves

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

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.
