valves & f i t t ings

Severn valves manufactured in SUFA alliance

Stainless steel components Béné Inox is a producer and distributor of technical stainless steel components for the construction and maintenance of fluid industrial processes. 30,000 products for different fields of application (including food industry, chemistry, cosmetic, pharmacy and oil) are presented in the company’s catalogues. Products for fluid processes include tubes, unions, valves, spigots, pipe fittings, flanges, measurement and instrumentation depending on standards ANSI, ISO, SMS and CLAMP. Available fastenings include screws, bolting and anchoring.

Each valve will be produced under agreement with Severn Ball Valves, as well as being tested and inspected in-house by the specialist’s experienced engineers before despatch. “Severn Ball Valves was established to offer good quality, reliable isolation valves backed up with engineering intelligence,” said Colin Findlay, managing director of Severn Ball Valves. “Our arrangement with SUFA proves that good value and exceptional quality can go hand-in-hand. When you have the technical knowledge and expertise to enhance the selection process, it is possible to offer traded goods with absolute confidence in their performance. These isolation valves will enable our customers to initiate cost- effective, technically assured upgrades at their facilities.”

The high-grade protection of steel surfaces is part of the standard delivery condition at Walter Stauffenberg. This also applies in the high-pressure ball valve segment, where the valves are given a zinc-iron coating. This not only enhances their appearance, but also provides additional protection against corrosion. Electrolytic plating with zinc upgrades the corrosion-protective properties. Surfaces were salt-spray tested to DIN EN ISO 9227 to determine the corrosion resistance. The result verified resistance to white rust for around 96 hours and to red rust for around 300 hours. Phosphating and yellow chromating rate were considerably lower. Contrary to yellow chromated zinc surfaces, whose corrosion-protective properties diminish when subjected to stressing by heat rising over 80 to 90°C, corrosion protection using a zinc-iron coating Global isolation valve specialist Severn Ball Valves, part of Severn Glocon Group, is now supplying a new Severn range of highly specified gate, globe and check valves from the Saudi Aramco-approved manufacturer SUFA Technology Industry Company. Stock is available from each of Severn Ball Valves’ trading hubs, strategically located in Aberdeen, Dubai and Perth (Australia) to serve the international market. Engineers have conducted extensive due diligence to underpin an assurance that the valves meet the exacting standards demanded by all Severn Glocon Group companies. Their inspection and testing procedures proved the quality of the valves, which meet or exceed requirements for applications associated with industries including oil and gas production, LNG processing and nuclear.

Surface protection for high-pressure ball valves

improves at temperatures of around 100°C.

The galvanically applied zinc- iron layer is free of chromium VI and complies both with the RoHS Guideline and with the EU End-of-Life Vehicle Directive 2005/53/EC. A further advantage is that the ball that forms the shut- off body within the valve is provided with hard chrome plating, which reduces the

friction and wear on the ball seat. High- pressure ball valves are available for pressures of up to 800 bar. Walter Stauffenberg GmbH & Co KG was founded in the 1950s in Werdohl, in the German province of North Rhine-Westphalia, and was initially a contract turning shop. The company currently operates under the

trade name Stauff, specialising in the development, production and marketing of fluid technology components for use in plant construction and mechanical engineering.
