Pneumatic Actuated 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.
