Forged Gate Valve
Introductions
The Forged Gate Valve functions as a pipeline cutoff, only allowing for full opening and full closing. When fully open, the medium in the valve body channel experiences almost zero flow resistance. This valve can be installed without regard for import and export directions, allowing for medium circulation in both directions. Forged Gate Valves are widely used in cold and hot water pipeline systems, particularly in large diameter pipelines.
The valve has a small fluid resistance and the sealing surface is less likely to be brushed or corroded by the medium. Additionally, its opening and closing requires less effort. The flow direction of the medium is unrestricted, allowing for uninterrupted flow and pressure. Furthermore, the valve has a simple shape, short structure length, good manufacturing technology, and a wide range of applications.

Advantages of Forged Gate Valve
The Forged Gate Valve has several advantages, including low fluid resistance, reduced susceptibility to brushing or corrosion by the medium, and ease of opening and closing. Its simple shape, short structure length, good manufacturing technology, and wide range of applications make it a versatile valve for many industries.
In addition, the Forged Gate Valve can operate in both directions, allowing for uninterrupted flow and pressure. Its seat rings are also renewable, which means they can be easily replaced to extend the life of the valve.
The Forged Gate Valve is also available in a variety of materials, including alloy 20, Monel, Inconel, and Hastelloy. This makes the valve suitable for use in applications where the medium is highly corrosive or abrasive.
