Valvola corpn offers forged bellow sealed globe valve which is similar to conventional forged globe valves, but metallic bellow assembly is provided for hermetic sealing of valve spindle. These valves are preferred where leakage from stuffing box is not permitted and used for critical services like chlorine, ammonia, and radioactive and thermic fluids. Spindle coming inside the valve body is covered completely by metallic bellow. Due to o s & y, rotary movement of hand wheel is converted into axial movement of valve spindle to open and close the valve. Axial movement of valve spindle does not allow any twisting force on the bellow during compression and expansion of the bellow. Bellow gets compressed when valve is fully open and bellow gets expanded when valve is fully closed. Forged bellow sealed globe valve with compact design are available in various moc like a 105, f 304, f 316, lf-2, lf-3, etc, and bellows in aisi 316ti/316/! monel 400/hastelloy c 276/1nconel 625, etc.
