The status quo and development trend of China's gate valve market

Gate valves have the longest history of use, and are still used in various countries around the world, especially below DN300mm, which still dominate in various types of valves. The characteristic is that the pressure difference between the front and rear of the valve plate forces the valve plate to press on the valve seat on the right side of the outlet, with good sealing performance, and when the valve plate is fully opened, the pressure loss is small because the valve plate does not remain in the flow path. Used to cut off the medium in the pipeline.
