Ball valve is designed for cryogen flow isolation at –196°C

US-based Flowserve Corp has intro-duced the McCanna CryoSeal ball

valve for cryogenic service.According to the company, which is a major

provider of flow-control products and services for the global infrastructure markets, CryoSeal repre-sents the optimum design for cryogen flow isola-tion at temperatures as low as –196°C (–321°F).

User benefits include increased uptime through the use of self-compensating, live-loaded stem seals that provide enhanced sealing life as well as leak-tight integrity. In addition, CryoSeal’s top-entry design enables in-line main-tenance, which further increases process uptime. The wedge seat design also compensates for wear and thermal cycling in various applications.

The valve has a number of features that make it ideally suited to various cryogenic applica-tions, including liquefied natural gas (LNG) liquefaction, transportation and re-gasification. Its quarter-turn operation and special low-torque seat profiles make it simple and cost-effective to automate, says the company. Particularly signifi-cant is the fact that it is certified as both fire-safe and meeting the ISO 15848 standard for fugitive emissions, making it an ideal choice for a num-ber of cryogenic applications.

Jeff Drees, President, Flow Control Division, Flowserve, commented: ‘With the introduction of the new McCanna CryoSeal ball valve, Flowserve has delivered a no-compromise system for the automated, or manual, control of cryogenic fluids by virtually eliminating all contamination, fluid degradation or waste, whilst assuring safety for people, property and the environment.’

The CryoSeal is available in sizes of 0.5–6 inches (15–150 mm) full port, or 0.5–8 inches (15–200 mm) reduced port, ANSI Class 150–600, with either butt weld or flanged ends. Both the body and bonnet are a one-piece construction for superior integrity and reliability.

The valve is certified to the following indus-try standards:

BS 6364 and API 608 – design and testing requirements;

(low emission); and

The American Association of Railroads (AAR) has approved the valve as suitable for use

on tank-cars, says Flowserve. This is significant not just because rail is an important means of transporting LNG and liquid nitrogen, but also as LNG is increasingly being used as an alterna-tive to diesel as a fuel for locomotives.

Perfluoroelastomer delivers excellent RGD resistance at low temperatures

Greene, Tweed & Co Inc, a manu-facturer of high-performance

elastomers, engineered thermoplastics, thermoplastic composites and integrat-ed materials, is offering a perfluoroe-lastomer which, it says, is designed to deliver exceptional chemical resistance and best-in-class rapid gas decompres-sion (RGD) resistance in environments involving extremely low temperatures.

Called Chemraz 678, it delivers the same chemical resistance as the company’s other compounds along with the ability to endure a wide temperature range of –40°C to 230°C (–40°F to 445°F). This material also provides excellent compression set and thermal shock resistance, enabling it to be used in a wide vari-ety of industry applications.

TriMas moves part of its gasket and fastener operations to MexicoTriMas Corp, a US-based diversified global manufacturer of engineered and applied products, has announced its final decision to move a portion of the gasket and fastener operations from its Lamons Houston facility to a new plant in Mexico. It says the move will improve the Lamons global operating model and enhance the competitiveness of the business. This transition is expected to be completed over the next 12 to 18 months.

David Hall appointed Head of Global Operations, James Dawson LtdIn the UK, James Dawson Ltd, which engi-neers bespoke silicone and organic rub-ber products, has appointed David Hall to the newly created position of Head of Global Operations. Paul Edwards, Managing Director, James Dawson, commented: ‘David is clearly a big hitter with diverse global man-ufacturing experience, and it is great to have him on board. One of his key tasks will be to influence strategic decisions in regards to where to increase our global manufacturing footprint now and in the future – whether that be in China or elsewhere – with a view to enhancing value stream without detriment to quality.’

Eaton’s FD85 Series thread-to-connect coupling is certified by Lloyd’sPower management company Eaton Corp has announced that its FD85 Series thread-to-connect couplings – in 0.75-inch and 1-inch sizes – now carry a Lloyd’s Registry certifi-cate for oil and gas applications as standard. Based on testing completed by a third party and witnessed by a Lloyd’s Registry auditor, the firm’s thread-to-connect couplings are certified as capable of maintaining pressures when exposed to a temperature of 700°C for a five-minute period.

Dow Corning becomes Bosch Group preferred supplierDow Corning Corp, which specialises in silicones and silicon-based technology, has been awarded what is referred to as the “Preferred Supplier” status in the elastomers and thermosetting plastics materials group by Bosch. This status is assigned once a year by Stuttgart-based Bosch, a major supplier of technology and services, to the best of its 4000 suppliers. Dow says that it enables it to be integrated even earlier into the German firm’s product development process.
