Triple eccentric valves for zero leakage Zwick Armaturen GmbH’s facility at Ennepetal, Germany, hosts 16,000m 2 of warehouses and machine shops with over 5,000 valves and ready to mount parts, making it one of the largest stocks of triple eccentric valves in the world. Zwick assures short-term delivery times and flexibility in material selection, even for materials such as Duplex, Super Duplex or bronze. tightness are essential for the user or operator. The valves are found mainly in applications of waste gases, liquids, hot water or steam, at low and high temperatures of up to 815°C. Other important markets include the chemical and petrochemical industry, especially in critical applications.

and body styles, including short and long pattern double flanged valves, lug- type or valves with buttweld ends, all in accordance to DIN, ANSI and API standards. Zwick is committed to offering environmentally friendly products, such as its stem packing design, which is certified as a low emission device, as per TA Luft II. All Zwick parts and manufacturing processes are conducted at the Ennepetal facilities, with no third party participation.

The standard portfolio of products starts with sizes from DN 50 to DN 1800 and pressure classes from PN 10 to PN 160 and corresponding inch diameters (2" to 72"), and ANSI pressure classes 150 to Class 900.

For more than 30 years, the company has manufactured valves for different industrial applications. Today, Zwick is focused on producing the TriCon series triple offset metal-seated butterfly valve. TriCon valves are used wherever reliable function and absolute

With the GLD 202, inspection of pipelines is easy. Analysis of the data is largely automated, so after short time of analysis, pipeline operators and inspection providers reliably know the state of the pipeline. For the first time, such pigging inspection can be carried out by non- experts. This is partly because the GLD 700 analysis software, running under Microsoft Windows, is very simple to use.

ATEX approval for Zone 0, the intelligent pig can be used in any liquid pipeline, without compromising operation. The GLD 202 leak detection system works by using multi-spectral analysis of events, and records the noise during the entire pipeline run every second on 128 channels. The data is suitable for an analysis of potential leaks, and also gives other information on the condition of the pipeline (eg wax deposits on pipe joints, movement of sliders). The North German company offers a small inspection pig that can be used in combination with the GLD 30x chassis in any pipeline with an inside diameter of 200mm (8") or more.

For cost reasons, many pipelines are only rarely inspected with smart pigs, because shutdowns for several inspections per year would mean huge economic losses. Real-time monitoring systems are a good way to detect large leaks, but even those are often difficult to locate. At worst, several hundred metres of pipeline must be uncovered and inspected – a disproportionate effort. Gottsberg Leak Detection has developed the GLD 202: a compact and robust leak detector that can be deployed easily and often. Pipeline operation is almost unaffected during pigging, and even the smallest leaks can be accurately detected and located. With
