Worcester Cryogenic Three-Piece and Flanged Ball Valves

Worcester Cryogenic Three-Piece and Flanged Ball Valves

The Worcester Cryogenic three-piece and flanged ball valves from Flowserve are engineered for optimal reliability and fugitive emissions compliance in critical service environments. These valves feature an innovative bolted cryogenic bonnet design and upgraded performance attributes. Compliant with API 641 and ISO 15848 standards for fugitive emissions, they are available in both three-piece and flanged configurations. Key features include standard fire-safe certifications, API 608 compliance, robust live-loaded PTFE packing, tongue-and-groove body joint sealing on three-piece designs, and a threaded end plug on all flanged sizes. These valves are built to meet leading cryogenic standards, including BS 6364, MSS SP-134, and ISO 28921, among others.
