There are five main product families: Marine Valves, Waterworks Valves, Oil & Gas Valves, Maritime (naval) Valves and Remote Control Valves. By type the range covers ball valves, butterfly valves, gate valves, globe valves, check valves, swing check valves, foot valves, firefighting and deckwash valves, quick closing and self closing valves, mud boxes, strainers and suction strainers.
Depending on the product family, DIN 86251 and DIN 3356 design standards and the EN 558 Series 1 (DIN 3202 F1) face-to-face standard are applied. Flanges are manufactured to EN 1092-2/B (DIN 2501) in PN 4/6/10/16 pressure ratings. Of the 1,120 products published in the catalogue, 941 reference a DIN standard in their technical specifications.
Bodies and bonnets are produced in cast iron (EN-GJL250 / GG25) and ductile iron (EN-GJS400-18-LT / GGG40.3); internals such as seats and stems are in stainless steel (X5CrNi18-10 / AISI 304 and X20Cr13 / AISI 420). Cast bronze bodies form a separate product group. The full material list of every product is given component by component in the table on its own page.
Six main areas are served: marine, defence, water and wastewater, oil and gas, energy, and industrial processes.
Yes. DIN 86 series marine valves form the core of the range and the products are type approved by classification societies. A separate product family is available for naval applications.
Yes. Both the marine valves and the oil & gas valves families include a dedicated firefighting and deckwash valve category.
Approvals are held from DNV, Bureau Veritas, Lloyd’s Register, RINA, Türk Loydu, NKK, CRS and RMRS. In addition there are TSE, TSEK, TÜV Rheinland, TÜV Austria, WRAS and IQR certificates. All documents are published as PDFs on the Certificates page.
Yes. The Dikkan Metal sand casting foundry casts iron, steel and bronze alloys, with an annual capacity of 12,000 tonnes and part weights from 50 grams up to 6 tonnes. The pattern shop, core shop, moulding, melting and grinding processes are all carried out in house.
In our R&D Centre casting processes are modelled with ANSYS based casting simulation, and patterns and prototypes are produced on 3D printers. The resin moulding line can cast parts up to 4000 × 4000 × 1500 mm.
Dikkan works as a B2B manufacturer and prices are set per project and quantity, so they are not published on the website. For a quotation please use the export department contact details on the Contact page.
Services include dismantling and assembly, fault analysis and reporting, maintenance and repair, corrosion protection, pressure and function testing, modernisation and commissioning. For valves that cannot be removed our service technicians attend site, and every repair carried out by Dikkan is covered by an “as new” guarantee.
