East Anglia ONE Offshore Wind Farm
The 714MW East Anglia ONE Offshore Wind Farm will be located approximately 43km off the Suffolk Coast in the southern North Sea, UK.
Sealand Engineering has been engaged in the design and manufacture of wedge gate valves for UK and overseas supply since 1953. Over the years, they have been in service in the following areas of industry – ships and seawater requirements, power generation, steam, water, sewage, firewater, and potable water. Our manufacturing capabilities range from one-off requirements to small batches and we have delivered individual products up to 2t in finished weight and up to 750mm (30in) bore.
We manufacture both rising stem and non-rising stem wedge gate valves and can provide valves made to your exact specification to our own designs using our own pattern equipment.
Our wedge gate valves are supplied with material certification in accordance with any requirement and, if requested, compliant with Classification Society Inspection; for example, Lloyds EMEA, ABS, BV and DNV.
All valves are 100% hydrostatically tested after assembly, in accordance with international standards, and air / gas testing as appropriate.
Sealand often supplies replacement heavy-duty wedge gate valves with channel guides, and often with flanges which are no longer in general production. These will typically be for power stations, water treatment and sewage treatment works.
All our valves are custom-designed to individual requirements and can incorporate the following more unusual features:
We use high-quality materials in the manufacture of our wedge gate valves. For body materials we use various grades of cast iron, SG iron, Ni-resist ductile iron, carbon steel, gunmetal, alloy steel, stainless steel, bronze, nickel aluminium bronze, alloy steel (for high temperatures) and stainless steel or Monel. All castings are sourced from UK foundries.
For bolting materials we use H.T. bolts, B7/2H stud bolting, B7M/2HM stud bolting, stainless E.G. B8MX stud bolting, aluminium bronze fasteners etc., as required.
Packing materials used include glassfibre and PTFE, Aramid fibre, and braided graphite.
For gasket materials we use non-asbestos, graphite coated, reinforced graphite, etc., which are spiral wound as required.
We offer a range of design, trim and flange options with our wedge gate valves.
