Forged Pressure Seal Gate Valve

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 gate valves are gate plates, and the movement direction of the gate plates is perpendicular to the direction of the fluid. The gate valves can only be fully opened and closed, and can not be adjusted or throttled. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used mode gate valves form wedges and wedge angles that vary with the parameters of the valve, usually 50 and 2 52'when the medium is not high. The sluice gate of a wedge valve can be made into a whole, called a rigid gate, or a sluice which can produce a small amount of deformation to improve its craft and make up for the deviation produced by the angle of the sealing surface in the process of processing, which is called an elastic gate.

The stem nut of the hidden gate valve is directly contacted with the medium in the valve body. When the gate is opened and closed, it is realized with the rotating stem. The advantage of this structure is that the height of the gate valve keeps constant, so the installation space is small, and it is suitable for large caliber or gate valves with limited installation space. Such a structure should be equipped with an opening and closing indicator to indicate the degree of opening and closing.
