Emerson Process Management introduces the Fisher® 8590 high-performance butterfly valve that brings a selection of disk seals, actuator designs and material combinations to meeting plant-wide throttling and on-off requirements.
Ben Fletcher, product manager at Emerson, explained the design intent behind the 8590 butterfly valve. “Our goal was to give application engineers the ability to combine a single valve platform with a selection of proven technologies to control a diverse range of CL600 process demands.”
“As an example, several dynamic disk seals are available in the 8590 design to meet temperature conditions that range from low-to-moderate up to 538°C (1000° F). Severe service and cryogenic applications can be met as well with the appropriate metal-polymeric or rugged stainless steel seal construction,” Fletcher added. “Since one valve design meets several needs, overall valve engineering, purchasing, installation, operation and maintenance costs become less.”
Utilizing a lugged body design across the CL600 size range of NPS3 – NPS24, the 8590 can incorporate a splined shaft that accepts either a spring-and-diaphragm or pneumatic piston actuator. It is also available with either a square or keyed shaft that combines with hand levers, hand wheels or pneumatic piston actuators.
