It provides the motorised movement needed to shift the valve between heating, hot water, or mid-position settings based on control system signals.\u003c\/p\u003e\n\u003ch3 data-start=\"342\" data-end=\"366\"\u003eFunction \u0026amp; Purpose\u003c\/h3\u003e\n\u003cp data-start=\"367\" data-end=\"891\"\u003eThis actuator receives electrical signals from room thermostats, cylinder thermostats, programmers, or heating control systems and uses them to move the linked 3-port valve to the correct position. In a mid-position valve setup, the actuator enables the valve to route hot water to the heating circuit, the hot water circuit, or both simultaneously when required. Replacing a worn or faulty actuator with the HSA3 restores smooth, reliable motorised control of the valve and precise water distribution in the heating system.\u003c\/p\u003e\n\u003ch3 data-start=\"893\" data-end=\"912\"\u003eCompatibility\u003c\/h3\u003e\n\u003cp data-start=\"913\" data-end=\"1256\"\u003eThe HSA3 actuator is designed specifically for Danfoss 3-port mid-position valve bodies that accept the \u003cstrong data-start=\"1017\" data-end=\"1031\"\u003e087N658700\u003c\/strong\u003e actuator. It interfaces with standard heating control signals and fits directly onto the matching valve body, making it suitable for use in central heating and hot water systems that use this type of motorised control valve.\u003c\/p\u003e\n\u003ch3 data-start=\"1258\" data-end=\"1277\"\u003eBuild Quality\u003c\/h3\u003e\n\u003cp data-start=\"1278\" data-end=\"1592\"\u003eManufactured to Danfoss quality standards, the HSA3 actuator is built for durability and long service life. Its internal motor and gearing provide reliable, quiet operation over repeated cycles, and the casing is designed to withstand the typical environmental conditions found in boiler rooms and heating systems.\u003c\/p\u003e\n\u003ch3 data-start=\"1594\" data-end=\"1618\"\u003eIdeal Applications\u003c\/h3\u003e\n\u003cp data-start=\"1619\" data-end=\"2020\"\u003eThis actuator is ideal for heating engineers, service technicians, and installers performing maintenance, diagnosis, or replacements on Danfoss 3-port mid-position valves. It is particularly useful where valve movement is sluggish, unresponsive, noisy, or fails to reach the correct position due to actuator wear or failure, helping to restore dependable control of heating and hot water distribution.\u003c\/p\u003e","brand":"Danfoss","offers":[{"title":"Default Title","offer_id":57055020056921,"sku":"118255","price":83.81,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0982\/9738\/1209\/files\/118255.jpg?v=1768302899","url":"https:\/\/plumbpartsxpressshop.com\/products\/danfoss-hsa3-3-port-mid-pos-actuator-only-087n658700","provider":"Plumbparts xpress","version":"1.0","type":"link"}
