It combines a durable valve body with a reliable actuator for precise control of water flow.\u003c\/p\u003e\n\u003ch3 data-start=\"338\" data-end=\"362\"\u003eFunction \u0026amp; Purpose\u003c\/h3\u003e\n\u003cp data-start=\"363\" data-end=\"961\"\u003eThis 3-port valve can direct water flow to heating, hot water, or both simultaneously, based on the demands of the system controls (such as a room thermostat, cylinder thermostat, or programmer). When there is a call for heat to radiators, the valve shifts to route flow to the heating circuit. When domestic hot water is required, it shifts to route flow to the cylinder. In mid-position, it can allow flow to both circuits if the control signal requires. This automatic switching improves comfort and system efficiency by ensuring water is delivered where it’s needed without manual intervention.\u003c\/p\u003e\n\u003ch3 data-start=\"963\" data-end=\"982\"\u003eCompatibility\u003c\/h3\u003e\n\u003cp data-start=\"983\" data-end=\"1306\"\u003eThe valve is designed for \u003cstrong data-start=\"1009\" data-end=\"1046\"\u003estandard central heating pipework\u003c\/strong\u003e (typically 22 mm or 28 mm depending on the specific variant) and works with common heating control systems that provide standard motorised valve control signals. The 087N661300 actuator is matched to the HS3 valve body to provide smooth and reliable movement.\u003c\/p\u003e\n\u003ch3 data-start=\"1308\" data-end=\"1336\"\u003eDesign \u0026amp; Build Quality\u003c\/h3\u003e\n\u003cp data-start=\"1337\" data-end=\"1641\"\u003eThe valve body is constructed from quality materials for durability, and the actuator provides dependable motorised control with quiet operation. The valve and actuator assembly is engineered to withstand the operational pressures and temperatures common in domestic and light commercial heating systems.\u003c\/p\u003e\n\u003ch3 data-start=\"1643\" data-end=\"1667\"\u003eIdeal Applications\u003c\/h3\u003e\n\u003cp data-start=\"1668\" data-end=\"2026\"\u003eThis 3-port valve is ideal for zoned heating systems where separate control of heating and hot water circuits is required. It is commonly used with conventional boilers and systems that have separate cylinder and radiator controls, and is suitable for new installations, retrofits, and replacements where automatic flow management between circuits is needed.\u003c\/p\u003e","brand":"Danfoss","offers":[{"title":"Default Title","offer_id":57054996070745,"sku":"121441","price":142.87,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0982\/9738\/1209\/files\/118261.jpg?v=1768222009","url":"https:\/\/plumbpartsxpressshop.com\/products\/danfoss-hs3-3-port-valve-actuator-087n661300","provider":"Plumbparts xpress","version":"1.0","type":"link"}
