Dredge Yard recently delivered dredge valves of 600mm, 700m and 750mm internal diameter for the discharge pipelines on two trailing suction hopper dredgers.
All of the dredge valves were designed by Dredge Yard’s team of engineers using the latest design software. Fabrication was done in-house at Dredge Yard’s production facilities.
One of the special features of the valve is a steel reinforced rubber seal, making the seal very durable, enabling it to cope with abrasive slurries and to be able to open and close smoothly in difficult working conditions.
The body of the dredge valve was fabricated from high tensile steel and the valve gate is made of corrosion resistant, hardened steel, protecting it against the rust and wear. The outer surface of the valve was coated with a high quality marine paint to protect it against corrosion.
The inspection hole placed in the both sides of the valve body allows for easy inspection without dismantling it.
