Dredge Valves

Our dredge valve designs are entirely scrutinized due to using Finite Element Analysis.

The dredge valves are designed in three different working duties, varying between 10, 20 and 30 bar. The dredge valve has an option of real time feedback for the position of the dredge valve gate. Dredge Yard valves are designed, produced under strict ISO and ASTM standards and are double tested at a third party for verification. All dredge valves are designed, produced, assembled, tested, painted, greased, packed and transported under close super vision of the quality control team of Dredge Yard.

Dredge Yard emphasizes on after sales and ensures total customer satisfaction.
