Butterfly Valves

Fouress Engineering offers Butterfly Valves. Features: Fouress-Boving butterfly valves are mechanically superior, structurally sound, of fool proof design, easy to operate and hence totally reliable; a streamlined disc profile provides smooth flow and ensures low pressure drop. Disc designed for strength and deflection eliminates possibility of flutter; single piece insitu replaceable seals in resilient rubber. This in conjunction with SS seat ring provides drop tight sealing. Seat ring is di-electrically insulated from the body to resist galvanic corrosion; static shaft seal in "O" ring/SCN ring construction; clamping ring is segmental form or in one piece. Segments facilitate uniform seal seating and local repair; thrust pad allows vertical shaft orientation. It also acts as centralising device for shaft disc assembly; drive shafts generously designed for transmitting maximum operating output; self-lubricating bearings capable of withstanding hydrostatic disc load and designed specially for edge loading characteristics; designed in such a way that the valve is suitable for both horizontal as well as vertical installation; specifically designed ebonite lined valve for sea water application, which is the most economical and reliable option for such difficult duties. Advantages: substantial saving on the basic cost of the valve, fully retains the advantage of a complete stainless steel valve; special self-energising sealing system to handle varying pressure conditions; etc. Dual seal arrangement disc incorporates an inflatable hose design to ensure on-load seal replacement.
