Built with a heavy-duty brass housing, this unit provides exceptional durability and outstanding resistance to demanding system environments. Its low-maintenance, high-performance architecture makes it an ideal solution for residential, commercial, and industrial hydronic application loops.\n  \u003c\/p\u003e\n  \u003cp style=\"margin-top: 15px;\"\u003e\n    Long recognized as the industry benchmark for regional thermal regulation, this motorized zone valve utilizes a robust heat-motor actuator to offer completely silent, twist-lock operation across multi-zone radiant and baseboard layouts. The iconic gold control head features an integrated end-switch that instantly signals the system circulator pump or boiler control terminal to fire up only when the valve is fully open. Engineered with a manual open lever to assist during system purging or emergency power outages, it delivers ultra-dependable fluid isolation and precise zoning control.\n  \u003c\/p\u003e\n\n  \u003c!-- Advanced Engineering Features Bullets --\u003e\n  \u003cdiv style=\"margin-top: 25px; margin-bottom: 20px;\"\u003e\n    \u003ch4 style=\"font-size: 16px; font-weight: bold; margin-bottom: 10px; color: #111111; border-bottom: 2px solid #111111; padding-bottom: 5px;\"\u003eAdvanced Engineering Features:\u003c\/h4\u003e\n    \u003cul style=\"margin: 0; padding-left: 20px; font-size: 14px; color: #333333; line-height: 1.6;\"\u003e\n      \u003cli style=\"margin-bottom: 8px;\"\u003e\n\u003cstrong\u003eIconic Gold Heat-Motor Design:\u003c\/strong\u003e Silent thermostatic expansion operator mechanism eliminates the loud water hammer and gear stripping common in motorized zone valves.\u003c\/li\u003e\n      \u003cli style=\"margin-bottom: 8px;\"\u003e\n\u003cstrong\u003eToolless Twist-Lock Assembly:\u003c\/strong\u003e Actuator head separates from the brass body with a simple twist, allowing rapid service upgrades without draining down the hydronic lines.\u003c\/li\u003e\n      \u003cli style=\"margin-bottom: 8px;\"\u003e\n\u003cstrong\u003eBuilt-In Auxiliary End Switch:\u003c\/strong\u003e Low-voltage end-switch isolates zones completely, preventing ghost flows and back-pressures across manifold links.\u003c\/li\u003e\n    \u003c\/ul\u003e\n  \u003c\/div\u003e\n\u003c\/div\u003e","brand":"Taco","offers":[{"title":"1\/2\"","offer_id":42913307885662,"sku":"570-2","price":107.0,"currency_code":"USD","in_stock":true},{"title":"3\/4\"","offer_id":42913146241118,"sku":"571-2","price":107.0,"currency_code":"USD","in_stock":true},{"title":"1\"","offer_id":42913146273886,"sku":"572-2","price":131.0,"currency_code":"USD","in_stock":true},{"title":"1-1\/4\"","offer_id":42913146306654,"sku":"573-2","price":167.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/Taco_570_Series_Gold_Motorized_Hydronic_Zone_Valve_with_gold_actuator_head_assembly_for_multi-zone_radiant_heating_lines..png?v=1781980175","url":"https:\/\/nationalboilersupply.com\/products\/taco-570-series-valves","provider":"National Boiler Supply","version":"1.0","type":"link"}
