{"product_id":"barber-coleman-ea57-actuator","title":"Barber-Coleman EA57 Actuator","description":"\u003cdiv\u003e\u003cp\u003eBarber-Colman EA57 Actuator is a non-spring-return, medium-torque rotary actuator designed for proportional positioning of fuel valves, dampers, and similar control devices in burner and process-control systems. It provides 90° of travel with a fixed 40-second timing and up to 220 in-lbs (≈25 N·m) of torque, making it suitable for moderate-load valve modulation. Powered from 120 VAC at 50\/60 Hz, the actuator includes a 100-ohm feedback slidewire and a single SPDT input switch for straightforward control. Typical applications include modulating fuel valves, butterfly valves, and dampers in burner management or combustion-control loops where precise, repeatable positioning is required. The EA57 family is compatible with Barber-Colman, Eurotherm, and Schneider Electric legacy systems, enabling retrofit in existing control architectures. With rugged industrial construction and a well-defined 90-degree travel profile, the EA57 offers reliable, long-term actuation for demanding industrial environments.\u003c\/p\u003e\u003c\/div\u003e","brand":"Barber-Coleman","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51676666036526,"sku":null,"price":725.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_04b3a78e-dfbf-4aed-b08a-04f1a8c39daf.jpg?v=1769552129","url":"https:\/\/plgautomation.com\/products\/barber-coleman-ea57-actuator","provider":"PLG Automation ","version":"1.0","type":"link"}
