Emerson Process Management - Fisher® ELS, EL, and EL Extended Series Electric Actuators EL-200

Optimum Performance Under the Most Demanding On/Off and Regulating Conditions From aggressive chemicals to use in hostile environments, electric actuators must provide optimum performance under the most demanding operating conditions. EL-O-MATIC ELS, EL, and EL Extended Series Electric Actuators meet this challenge through a superior design that is field-proven over a wide range of process applications and uses high quality, corrosion-resistant aluminum alloy, stainless steel, and bronze materials for internal components and housings. ELS Series Electric Actuators are available in two (2) models, produce up to 221 lb.in. of torque and utilize a spur gear drive system effective for use with 2-way and 3-way ball valves. Standard operating features include cam operated limit switches from 0° to 270° of rotation and 50% duty rating. Options include two extra switches for auxiliary circuit control, feedback potentiometers, MOD positioner (ELS 25 only) for position control, compartment heater, low voltage DC motors for vehicular applications and special paint or labeling.
