May 26, 2009 – Emerson Process Management introduces the Fisher 2052 spring-and-diaphragm rotary actuator. The compact actuator reduces valve/actuator envelope dimensions to provide greater valve installation versatility for both skids and tight processing lines where space is at a premium.The new Fisher 2052 actuator can be installed on rotary-shaft valve bodies for throttling or on-off applications. The actuator linkage features a clamped shaft lever and a single pivot point to reduce lost motion between the actuator and the valve. The result is 0.5% or less typical variability for a Fisher rotary control valve assembly.In addition to its small size, the Fisher 2052 delivers several operations and maintenance advantages. It has an inherent failsafe position on loss of operating air. In contrast to piston style actuators that rely on O-ring seals, the double-sided diaphragm in the 2052 provides a longer service life.The Fisher 2052 actuator offers a unique, nested spring design that requires no bench set, simplifying the actuator selection process. Powder paint coating is standard and offers an excellent corrosion-resistant finish on all external steel and cast iron parts. The new Fisher 2052 actuator is available in three sizes, accommodating shaft sizes 12.7 to 38.1 mm (1/2 to 1-1/2 inch).About Emerson Process Management.Emerson Process Management, an Emerson business, is a leader in helping businesses automate their production, processing and distribution in the chemical, oil and gas, refining, pulp and paper, power, water and wastewater treatment, food and beverage, life sciences and other industries.
