As part of the Emerson EX8 Series, it supports refrigerants R134a, R404A, R407C, R410A, and R507, with a maximum operating pressure of about 45 bar and a 10–100% modulation flow range. It mounts inline with brazed or ODF fittings and requires an external controller (stepper driver) to operate. Maintenance teams and system integrators use this valve for refrigeration system optimization and replacement of failed or outdated expansion valves. Common applications include chillers, heat pumps, cooling systems, cold storage facilities, and industrial process cooling where precise refrigerant control maintains temperature stability and overall performance. Replacements or equivalents include Emerson EX8-U21, Danfoss ETS Series, and Carel EEV Series.\u003c\/p\u003e\u003c\/div\u003e","brand":"GE Fanuc Emerson","offers":[{"title":"New","offer_id":50558378311982,"sku":"New","price":1704.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/12.jpg?v=1752132333","url":"https:\/\/plgautomation.com\/products\/emerson-ex8-m21-electronic-expansion-valve","provider":"PLG Automation ","version":"1.0","type":"link"}
