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.

A waterproof, mildew resistant, cover for a water backflow prevention apparatus is provided that provides protection of the apparatus's control from UV damage is provided. The cover is constructed from a closed-cell polymeric foam and can be cut to fit when installed. The cover can be anchored to stakes in the ground to prevent dislodgment by wind or animals. The installed cover's open end can take advantage of heat in the ground to maximize the cover's internal temperature when the cover is exposed to low air temperatures.

A valve stem cover includes a cylindrical cap open at a bottom end thereof and threaded with threads on an inside surface thereof. The cylindrical cap is adapted for threaded engagement with a threaded tire valve stem that projects through a wheel rim. A skirt projects downwardly from the bottom end of the cylindrical cap and is adapted to cover substantially a lower portion of a threaded tire valve stem that projects through the wheel rim. A decorative top portion projects upwardly from a top end of the cylindrical cap and can be removable for interchangeability.

An in situ retrofit assembly for a top entry valve includes an annular conduit (100) configured to conform with a seat support (106) at the distal end (207) and a valve body extension (208) with an interior annular region (301). The valve body extension (208) comprises an inlet port (209) fluidically connected to the annular area (301). A gland packing push plate (211) is configured to allow the annular conduit (100) to pass through thereby forming an outlet port (212). This allows the removal of a portion of the fluid from the cold box for downstream processing or manipulation as desired.
