The idea first appeared in the early years of the 20th century, but it was the Bristol engine company that made sleeve valves
its own from the 1920s onwards, and thousands upon thousands of sleeve-valve Bristol radials hauled Bomber Command across Germany from 1939 onwards.
In operation, the rotary sleeve valve
rotates within the valve body, literally wiping away trace residue and preventing the accumulation of soot and other substances.
The Inbal valve is much more resistant to severe surge pressures than any other deluge control valve on the market, including other rubber sleeve valves
Working in a major hydraulic company some years ago I noticed a sudden increase in the output of the selectively assembled spool and sleeve valves
Tenders are invited for Provide sleeve valves
manufactured by pratt or bailey valve.
The plant also will accommodate seven, large-diameter pressure-control or sleeve valves
that will release water back into the nearby San Diego Canal for distribution.
