Dredge Gate Valve

Dredge Gate Valve

Application

A dredge gate valve is a specialized type of valve used in dredging operations to control the flow of water and materials through pipelines. It is typically installed in the discharge pipeline of a dredger, allowing for the regulation of material discharge and water flow during dredging activities. The dredge gate valve is designed to withstand the harsh conditions encountered in dredging operations. It is typically made from durable materials such as cast iron or steel to provide strength and resistance to corrosion. The valve is equipped with a gate or blade that can be raised or lowered to control the flow of materials.
