Expanded range of medium-pressure ball valves

Swagelok Company has released a larger size of its FKB series medium- pressure ball valve. Designed for improved cycle life in the field, the trunnion-style ball valves provide a leak- tight seal for applications up to 15,000 psig (1,034 bar) and feature Swagelok’s patent-pending direct load design, which delivers a consistent seal across a full range of pressures. Innovative stem and end connection seals prevent shell leakage and provide robust cycle life even in severe conditions. The two-way 8FKB ball valve complements the original 6FKB ball valve introduced in May 2009. The 8FKB ball valve, with a 9.52mm (0.375") orifice, offers ½" gaugeable Swagelok medium- pressure tube fitting end connections or ½" female NPT. The 6FKB ball valve is available with 5.31mm (0.209") orifice Flowserve Corporation, a provider of flow control products and services for the global infrastructure markets, has secured two multimillion-dollar orders from China Nuclear Power Engineering Co Ltd and China Nuclear Energy Industry Corp, for main steam isolation valves (MSIVs). The Flowserve Edward MSIVs are planned to be used at the CPR-1000 design Fuqing Units 3 and 4, and Tianwan Units 5 and 6. All four units are currently under construction and scheduled to be operational in 2016 and 2017, respectively. “These orders further strengthen our long-standing relationship with the Chinese nuclear power industry and with our customers, CNPE and CNEIC,” said Tom Pajonas, president, Flowserve flow control division. “We are pleased to be able to supply the products that help power the future of nuclear energy in China.”

All valves feature 316 stainless steel body construction and reinforced PEEK seat seals. The valves are rated for temperatures from -17° to 121°C (0° to 250°F) and maintain

a full pressure rating throughout the entire operating temperature range. Multiple O-ring materials are available, including nitrile, fluoroelastomer and perfluoroelastomer. Swagelok medium-pressure ball valves deliver reliable and repeatable operation to meet the performance requirements of common off-shore applications, such as topside wellhead control panels, chemical injection panels, well

workover panels and control systems. Maintaining the integrity of the valve seal is critical for applications where positive shut off is required. A bottom- loaded stem design eliminates stem blowout for enhanced operator safety. The FKB series features low-torque actuation, eliminating the need for assist methods and accessories in manual actuation. If pneumatic actuation is required, the valves are available with ISO-5211 compliant actuators. A positionable handle provides flexibility in panel layout by reducing clearance issues with other components. Swagelok medium-pressure tube fitting end connections provide single turn makeup, or makeup by torque, for reduced installation time and labour costs. Like traditional Swagelok tube fittings, the end connections employ a two ferrule design to deliver robust tube grip, leak-tight gas seal, and vibration resistance. Designed for the higher working pressures of the oil and gas industry, the Swagelok line of medium pressure products also includes medium pressure fittings and seamless tubing. The all 316 stainless steel fittings are available in a variety of configurations for use with medium pressure stainless steel tubing, both heavy wall annealed and cold-drawn 1 / 8 hard, and SAF 2507 ™ super duplex tubing.

Valve orders from Chinese nuclear firms

China Nuclear Power Engineering Co Ltd was established under China National Nuclear Corporation in 2007. Its main functions include nuclear power and other nuclear engineering, engineering construction consultation and training, nuclear power project management and nuclear power technology transfer. China Nuclear Energy Industry Corporation is a China National Nuclear Corporation subsidiary, established in 1980 as a trading company authorised to carry out import and export trade of uranium products, nuclear fuel cycle, and nuclear power and technology equipment. Valves included in the orders will be manufactured at the Flowserve facility in Raleigh, North Carolina.
