DN400 Dredge Gate Valve

DN400 Dredge Gate Valve

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.
Advantages
1.Dredge gate valves are developed,according to the specific requirements of pipe used for dredger.
2.Dredge gate valves drived by hydraulic cylinder and sealed by rubber.
3.Stainless steel wedge gate and heat-affected valve body.
4.Simple structure,high quality .
5.Main mediums are sewage,water and oil.
6.Types:switch type and contious display type.
7.Pressure up to 2.5Mpa.

Material
1.Hydraulic cylinder:body steel45,piston rod 1Cr17Ni2
2.Valve bady:Q235,16Mn.
3.Valve gate:stainless steel.
4.Seal:NBR,NR.
5.Fastener:Q235,steel 45,stainless steel.
