The actuator operates on 230 V AC and provides reliable open\/close action of the valve body with closing times of up to 20 seconds and opening times up to 35 seconds. It features a built-in SPST auxiliary switch for indication or interlocking functions, with output ratings of 3 A resistive and 1 A inductive�enabling integration with control panels or building management systems. Its compact dimensions (approx 63 � 86 � 73 mm) and weight (~0.53 kg) make it compatible with a wide range of valve bodies and system layouts. Designed for durability, the HSA3 actuator meets WEEE and REACH requirements and is covered by a two-year manufacturer warranty. It is commonly used in both domestic and commercial central-heating applications to control valve movement, enabling correct routing of flow, mixing or diverting circuits, and efficient heating system operation. Installation is straightforward and the actuator serves as a direct replacement for compatible motorised valve heads, avoiding the need to replace the entire valve body.\u003c\/p\u003e\n\n\u003c\/body\u003e","brand":"Danfoss","offers":[{"title":"Default Title","offer_id":56793722061184,"sku":"2200049","price":44.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/0629\/4936\/files\/308bba89-d1f4-444a-9a00-3ecd5ca3f080.jpg?v=1761836801","url":"https:\/\/www.lavastore.co.uk\/products\/danfoss-hsa3-3-port-valve-actuator-087n6587","provider":"Lava","version":"1.0","type":"link"}
