Forged Bellow Sealed Gate Valve
The opening and closing parts of Forged Steel Bellows Gate Valves are plug valves, the sealing faces are flat or conical, and the disc moves along the centerline of the fluid in a straight line. The motion form of the stem has the lifting rod type (the stem lift, the handwheel not lifting), also the lifting and rotating rod type (the handwheel and the stem rotates with the lift, the nut is located on the body). The corrugated valve is only suitable for full opening and full closing, and no adjustment and throttling are allowed. Valves of this type should be installed horizontally in pipes.
