What Is A Forged Steel Gate Valve?

The forged steel gate valve is much more detailed than the ordinary gate valve, and its various performances are also better. Especially in the case of high pressure and high temperature, the forged steel gate valve can adapt to this kind of working condition very well. However, forged steel valves also have a defect, that is, they are relatively easy to rust and corrode, and they are not as good as stainless steel gate valves in terms of acid and alkali resistance.

The so-called forged steel gate valve, as the name suggests, refers to a gate valve made of forging materials, such as A105, F11, F5, 304, 304L, 316, 316L, and so on.

The forged steel gate valve is used to cut off or connect the medium in the pipeline. Different materials are used, which can be respectively applied to various media such as water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea, and so on. It is widely used in oil pipelines.

Most of the forged steel gate valves are of the Dalian type reduced-diameter design. Compared with the cast steel gate valve of the same diameter, the flow rate is slightly smaller, but the pressure and temperature range of the forged steel gate valve is higher than that of the cast steel valve, and the sealing performance is much better than that of the cast steel gate valve. , longer life and the flow direction of the medium is not restricted like other gate valves.
When maintaining the forged steel valve, attention should also be paid to the problem of water inflow in the electric head and its transmission mechanism. Especially the rain that seeps in during the rainy season. One is to rust the transmission mechanism or the transmission sleeve, and the other is to freeze in winter. When the electric valve is operated, the torque is too large, and the damage to the transmission parts will make the motor no-load or over-torque protection trip, and the electric operation cannot be realized. The transmission parts are damaged, and manual operation cannot be carried out. After the over-torque protection action, manual operation is also unable to switch, such as forced operation, which will damage the internal alloy parts.

The domestic forged steel gate valve has developed to a certain level. Although there is still a certain gap compared with foreign valve casting technology, this gap is gradually narrowing. The quality of domestic forged steel gate valves is also getting better and better and has been unanimously affirmed by users. It is believed that in the future development process, the forged steel gate valve will become more and more perfect, and its functions will become more and more complete.
