These ball valves minimize leakage and emissions

| By Mary Page Bailey

Worcester 51/52 Series reduced-port flanged ball valves (photo) have been reengineered for global availability by standardizing the valves’ design, materials, construction and product certifications. The bubble-tight shutoff design and robust, live-loading packings in these valves minimize fugitive emissions, enhance safety and maximize regulatory and standards compliance. Featuring a redesigned end plug, the valves ensure positive retention and greatly reduce blowout risk. Low operating torques allow for compact actuator operation, reducing space and cost requirements. Operating temperature limits are –196 to 300°C (–320 to 572°F). — Flowserve Corp., Dallas, Tex.
