Dredge valve is used to control the flow of water and sand in the suction and discharge pipes of either cutter suction dredgers or trailing suction hopper dredgers.
The dredge valve is designed in such a way that there are no fasteners inside the body that can loosen and damage other parts during operation. On the other side, all the connections outside the dredge valve body are bolts and nuts that can be easily replaced without damaging any part of the body.
Two inspection holes located on both sides of the dredge valve allows an easier way of inspecting inside of the dredge valve body without dismantling any part of it.
Dredge valve is designed to cope with a large amount of abrasive slurries and to close and open smoothly in these tough conditions. For this reason Dredge Yard has designed a steel reinforced rubber seal hardened at both ends to ensure long life time and interchangeable in all directions.
The body of the dredge valve is made of cast steel and fabricated high tensile steel. The dredge valve gate is made of corrosion resistant and hard steel, protecting it against the rust and wear.
The dredge valves are designed in three different working pressures varying between 10, 20 and 30 bars according to the customer’s requirements and applications.
All dredge valves are designed, produced, assembled, tested, painted, greased, packed and transported under close super vision of Dredge Yard team of engineers and quality control.
