It operates on 120 V AC at 60 Hz, drawing about 0.65 A with a 40 W input, and mates to a 1\/2\" NPT valve via the 2-3706 connection, with a typical full-stroke time around 40 seconds and about 200 lb-in of torque. Designed as a direct retrofit for Barber-Colman, Eurotherm, and Schneider Electric units, the EA57 family provides dependable positioning without a return spring and is commonly used for burner control, fuel-air ratio systems, dampers, and other combustion-control applications in asphalt plants and similar industrial environments. The EA57-2-3706 pairing specifies a valve body sized for 1\/2\" NPT interfaces, enabling straightforward replacement of legacy actuators with verified compatibility and streamlined integration into existing control circuits.\u003c\/p\u003e\u003c\/div\u003e","brand":"Barber-Colman","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51676666626350,"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_f3039aeb-e02c-4592-a7e1-c519d9aaa5b9.jpg?v=1769552136","url":"https:\/\/plgautomation.com\/products\/barber-colman-ea57-2-3706-electric-valve-actuator","provider":"PLG Automation ","version":"1.0","type":"link"}
