Application
The DN400 dredge gate valve is a specific type of gate valve designed for use in dredging operations. The DN400 designation refers to the nominal diameter of the valve, which is 400 millimeters. This size is suitable for pipelines with a diameter of DN400. The DN400 dredge gate valve is constructed using durable materials such as cast iron or steel to withstand the demanding conditions encountered in dredging operations. These materials provide strength, corrosion resistance, and longevity to the valve.
