This magnetic rotation valve opener lets you manually test whether the valve core is movable before welding, ruling out simple jams without tearing down the entire refrigeration circuit. Save hours of labor, expensive refrigerant and new valve parts for every AC repair job.\u003c\/p\u003e\n\u003ch3\u003eMagnetic Rotation Manual Test Mechanism\u003c\/h3\u003e\n\u003cp\u003eThis specialty repair tool uses strong built-in magnetic force to directly drive the internal valve core after removing the original EEV coil. Simply slip the blue aluminum sleeve over the valve body, then twist the outer shell clockwise or counterclockwise to manually actuate the valve spool. You can instantly judge if the expansion valve core is seized or just a coil failure, avoiding blind disassembly and welding for fully functional valves.\u003c\/p\u003e\n\u003ch3\u003ePrecision 17.35mm Inner Diameter Universal Fit\u003c\/h3\u003e\n\u003cp\u003eEngineered with a ≤17.35mm inner bore, the sleeve perfectly matches the outer diameter of mainstream Shunguan and standard electronic expansion valve bodies widely used in residential and commercial air conditioners, heat pumps and refrigeration units. The tight tolerance aluminum sleeve fits snugly without wobble during rotation testing, delivering stable magnetic transmission for accurate valve core diagnosis.\u003c\/p\u003e\n\u003ch3\u003eDurable CNC Blue Anodized Aluminum Construction\u003c\/h3\u003e\n\u003cp\u003eThe entire tool body is made of lightweight solid aluminum with bright blue anodized anti-corrosion finish:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWear-resistant surface resists scratches, oil stains and refrigeration fluid corrosion from workshop environments\u003c\/li\u003e\n\u003cli\u003eRigid one-piece machined structure maintains round shape after thousands of clamping \u0026amp; rotation cycles\u003c\/li\u003e\n\u003cli\u003eCompact ring-style design fits easily into technician tool bags, no bulky extra attachments required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e3-Step Fast Operation, Zero Complex Modification\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eRemove the original electromagnetic coil from the top of the electronic expansion valve\u003c\/li\u003e\n\u003cli\u003eSlide this magnetic opener sleeve fully over the exposed valve body\u003c\/li\u003e\n\u003cli\u003eRotate the outer aluminum housing clockwise \/ counterclockwise to manually drive the internal valve core and test mobility No cutting, welding or refrigerant discharge needed for preliminary fault screening—complete pre-welding inspection in under one minute.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch3\u003eEssential Refrigeration Workshop Troubleshooting Accessory\u003c\/h3\u003e\n\u003cp\u003ePerfect for professional HVAC repair shops, appliance service technicians and refrigeration maintenance teams:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eQuickly distinguish between faulty coil damage vs seized valve core failures\u003c\/li\u003e\n\u003cli\u003eEliminate wasteful full valve replacement when only the coil needs swapping\u003c\/li\u003e\n\u003cli\u003eReduce refrigerant loss, welding material consumption and customer repair downtime\u003c\/li\u003e\n\u003cli\u003eCompatible with most split AC units, cabinet air conditioners, heat pump water heaters and cold storage electronic expansion valves\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"YJGM","offers":[{"title":"1PCS","offer_id":48269158940857,"sku":null,"price":19.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/8497\/2473\/files\/01_19d1483e-46f8-4fdf-b5e2-da4142436fc8.jpg?v=1784627251","url":"https:\/\/gzgtool.com\/products\/electronic-expansion-valve-opener-magnetic-rotation-test-tool","provider":"YJGM LLC","version":"1.0","type":"link"}
