Flowserve McCanna introduces cryogenic valve
Flowserve, a provider of flow control products and services, has launched the McCanna CryoSeal ball valve for cryogenic service. The CryoSeal represents the optimum design solution for cryogen flow isolation at temperatures as low as -196⁰C.
User benefits with this new product include increased uptime through the use of self-compensating, live-loaded stem seals which provide enhanced sealing life as well as leak-tight integrity. The CryoSeal's top-entry design allows in-line maintenance which further increases process uptime. The wedge seat design compensates for wear and thermal cycling in various applications.
This latest development from Flowserve McCanna offers a number of features which make it ideally suited to various cryogenic applications including liquefied natural gas (LNG) liquefaction, transportation and regasification. Its quarter turn operation and special low-torque seat profiles make it simple and cost-effective to automate.
The CryoSeal is certified as both fire-safe as well as meeting the ISO15848 standard for fugitive emissions, making it an ideal choice for a number of cryogenic applications.
The CryoSeal is available in sizes 0.5 to 6" full port or 0.5 to 8" reduced port, ANSI Class 150 - 600, with either butt weld or flanged ends. Both body and bonnet are one-piece construction for superior integrity and reliability.
The valve is certified to these industry standards: BS 6364 and API 608 – design and testing requirements; API 607 and ISO 10497 – fire test; ISO 15848-1 fugitive; emission testing (Low E); API 598 testing.
The American Association of Railroads has approved the valve as suitable for use on tank cars. 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 alternative to diesel as a fuel for locomotives.
