Cryogenic Valve from Flowserve Designed to Help Control Fugitive Emissions

Flowserve Corporation, a global provider of flow control products and services for the infrastructure markets, announced the launch of the Worcester cryogenic series of reduced-port, quarter-turn floating ball valves for liquefied natural gas (LNG), hydrogen, and other industrial gas and cryogenic applications.

Available in three-piece (CF44 series) and flanged (CF51/CF52 series) configurations, Worcester cryogenic valves feature a high-strength stem and provide exceptional fugitive emissions control from an improved live-loaded stem seal. They also incorporate a modular bolted bonnet design, which provides customers with cost-effective flexibility and enables them to reduce spare parts inventories. Total cost of ownership (TCO) is reduced as a result.

“Worcester cryogenic ball valves meet global fire-safe and fugitive emissions standards, including testing with hydrogen. As a result, they support energy transition initiatives and hydrogen production while ensuring fugitive emissions containment. In addition, the global certifications compliance ensures reliability and peace of mind in all cryogenic applications,” said Daniel Dillon, global product leader specialty ball valves at Flowserve.

Worcester cryogenic valves can be key enablers in several industries, including aerospace, food and beverage, defense, pharmaceutical, petrochemical, steel and biofuels. Flowserve-engineered Worcester cryogenic valves can be utilized for LNG applications including gasification, loading and unloading, processing, refrigeration and transportation. They’re also designed to meet requirements for processes involving hydrogen, nitrogen, oxygen and ammonia.

The redesigned bonnet configuration offers robust stem sealing for fugitive emissions compliance throughout the thermal ranges. Live loading ensures a long service life and continued compliance. The high-strength stem improves reliability, extends service life, and provides for increased maximum allowable stem torque (MAST) while complying with API 608 and ISO 17292.

“Our Worcester cryogenic ball valves are third-party tested to the latest fugitive emissions standards using hydrogen, so customers can be confident that the valves will support sustainability efforts and reduce greenhouse gas emission,” Dillon said.

The cryogenic bolted bonnet provides a standardized modular design for flanged and three-piece valve models, enabling companies to reduce spare parts inventories and TCO. Both models meet global certification requirements for API 607, API 641, ISO 15848 and PED.

The modular bolted design also simplifies maintenance compared to the previous conventional welded design. Customers also benefit from worldwide availability and competitive lead times now possible because Flowserve standardized the Worcester Cryogenic valve design, materials and construction.
