Forged Steel Gate Valve

The DIN Cast Steel Gate Valves are widely used in oil and steam pipelines, such as chemical industry, fire power plant, power plant, etc., for opening or closing the medium in the pipeline., including DIN F5、DIN F7、DIN F4 Rising Stem Gate Valve, DIN F15 Non-Rising Stem Gate Valve, DIN F1、DIN F2 Globe Valve, DIN F32 Angle Globe Valve, DIN F1、DIN F6 Swing Check Valve, DIN F1 Lift Check Valve, DIN Cast Iron Valve etc, Our products are utilized widely in oil, gas, hydraulic, refining chemicals, petrochemicals, pharmaceuticals, food industries, fire-safe systems, marine systems and power stations, etc.

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.

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.
