The DN900 dredging gate valve works by opening or closing the valve to control the flow of water or liquid. It is a valve specifically designed for use in dredging operations. It is often a large-sized valve with a diameter of 900 millimeters (about 36 inches) and is used to control the flow of water, slurry, or other materials in dredging applications. The valve is designed to withstand the harsh conditions encountered in dredging operations, such as abrasion, corrosion, and high pressure. It is typically made of heavy-duty materials such as cast iron, stainless steel, or other durable alloys to ensure long-term performance in demanding environments.
