Dredge Yard Valves for Two TSHDs
Dredge Yard has successfully delivered dredge valves of sizes 600, 700 and 750 mm internal diameter, needed for the discharge pipeline on board of two trailing suction hopper dredgers.
Fabrication was done in-house at Dredge Yard’s production facilities.
Dredge gate valves are highly sophisticated components, and for proper functioning, maintenance and long life it is very important to select the right type with the right material and pressure handling capability.
One of the special features of the valve is the steel reinforced rubber seals making the seal very durable, making it easy to cope with the large amount of abrasive slurries and to be able to open and close smoothly in tough working conditions.
The body of the dredge valve was fabricated from high tensile steel and the valve’s gate is made of corrosion resistant and hardened steel, protecting it against the rust and wear. For conservation of the outer surface of the valve a high quality marine type paint was applied to protect it against corrosion.
The inspection hole placed in the both sides of the valve’s body, allows for easy inspecting the dredge valve without dismantling it.
These types of dredge valves can be produced for three different working duties varying between 10, 20 and 30 bar according to the customer’s requirements and applications.
