Forged Bellow Sealed Gate Valve

KOSEN VALVE is specialized in manufacturing Socket Welding Forged Gate Valve with following good characteristics: good sealing performance, reliable safety guarantee, long life span and etc. Socket Welding Forged Gate Valve is usually used for DN40 for its economic features, and butt welding ends is for DN40. Socket welding is widely used for small size pipe because they would always have a thin wall thickness which may have problems for butt welding. Moreover, the birdsmouth part of socket welding has the function of reinforcement so that it is also welcomed under high pressure.

Forged steel gate valve refers to the closing piece (gate) along the path of the central line of the vertical movement of the valve. The forged steel gate valve is mainly cut off in the pipeline. Forged steel gate valve is a widely used valve, and its general caliber DN or less 50 cutting device selects it. Forging steel gate valves are more common.

The opening and closing parts of forged steel gate valves are gate plates. The movement direction of the gate is perpendicular to the direction of the fluid, and the forging gate valve can only be fully opened and closed, and can not be adjusted and throttled. The gate of the forging gate valve has two sealing surfaces. The two sealing surfaces of the most commonly used gate valves are wedge-shaped and wedge angles vary with valve parameters.

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.
