Abstract
An inline control valve (10-10F) having a fixed diverter member or plug (34-34F) positioned centrally of the flow passage (30-30F) and a sleeve (40-40F) mounted for movement between open and closed position relating to the plug (34-34F). One embodiment (FIGS. 2-4) includes a solenoid (72) for moving the sleeve (40) to an open position. A radially expandable metal seat ring (50) shown carried by the sleeve (40) in FIG. 4 seals against the plug (34) by radial expansion of the seat ring (50) relative to the sleeve (40). Another embodiment shown in FIGS. 5 and 6 includes a separate source of pressurized fluid (72A) for movement of the sleeve (40A) to an open position. The inline control valve (10F) is utilized in the embodiment of FIGS. 11-14 in combination with an indicator member (47F) to indicate an excessive fluid pressure.
