Dredge Yard - Dredge Gate Valve

• The dredge valve is designed in such a way that there are no fasteners inside the body
• Dredge valve is made of fabricated high tensile steel and cast steel
• The dredge valve gate is made of corrosion resistant and hard steel
• All dredge valves are operated by hydraulic cylinder located on the top of the dredge valve
• The dredge valve body is stiffened with T-bars
• The dredge valve body is is provided with inspection holes on both sides
• Steel reinforced rubber seals are used to seal the pipe when the gate is down
• Seals can be used both sides and turned in opposite direction when worn out
• The rubber seals are hardened where necessary to increase the life time of the seals
• All connections outside the body are bolts and nuts
• The fabricated body is made from high tensile steel
• Two flushing pipes are provided in the lower body of the dredge valve
• Hoisting lugs are provided on the top of the body

• No fasteners inside the dredge valves that can loosen and damage other parts during operation
• Corrosion resistant and hard dredge valve gate ensures longer life time
• Steel reinforced rubber seals hardened at both ends to ensure long life time and interchangeable in all directions
• All connections outside the dredge valve body are bolts and nuts that can be easy replaced without damaging any part of the body
• Compact design due to the use of high tensile steel
• Inspection holes allow easy inspection without dismantling the dredge valve body
• Different duties being 10, 20 and 30 bar to fit the right application
• The dredge valve can be delivered with visual and digital position indicator
• Easy handling and installation due to hosting lugs and compact design

To ensure a heavy duty design for obtaining a high reliability and efficiency performance the dredge valve are made out of the following materials:

• All dredge valves products are designed according to the customer`s requirements and applications using 3D CAD technologies
• The design is tested by Dredge Yard experts using Finite Element Analysis. External and internal forces are examined and all maximum possible scenarios are simulated
• Before making the pattern, casting simulation software is run to verify that all thickness, curves and radii will be obtained and the material will cool down in a good way preventing internal and external shrinkages
• The patterns are made from aluminum or wood depending on the quantities
• Casting is done in a clean and supervised environment. All necessary measurements are taken to obtain a good casting like using filters, special cast ladles, and strong paint for the mold surface
• All castings of dredge valves are heat treated according ISO and ASTM standards
• For all casting the mechanical and chemical properties are verified at third party
• After casting and after machining Dredge Yard team of quality control inspects all the parts to make sure that the quality will be according to customer`s and Dredge Yard`s specifications
• After approval of the products the cast surface is painted and the machined surfaces are greased
• The packing and transport is done under the supervision of Dredge Yard team to ensure the release of products in the right way

To ensure a heavy duty design for obtaining a high reliability and efficiency performance the dredge valve are made out of the following materials:

• Dredge valve body is made of high tensile carbon steel
• Dredge valve gate is made out of corrosion resistant and hard steel
• The seals are made from steel reinforced rubber hardened at both ends
• Lower body is made out of cast carbon steel

Dredge yard dredge valves can be delivered with the following options:

• Additional mechanical position indicator on the top of the dredge valve
• Proximity sensors attached to the hydraulic cylinder
