Fabricated with a heavy brass body featuring 3\/4\" female Sweat threaded connections, this low-voltage 2-way valve controls water loop distribution safely across individual baseboard headers, radiant loops, or terminal fan coils. Driven by a dependable 24V synchronous motor paired with a spring-return mechanism, the valve fails safely to a completely closed position during any localized power interruption.\u003c\/p\u003e\n\u003cp style=\"margin-bottom: 12px;\"\u003e\u003cstrong style=\"font-size: 15px; color: #111;\"\u003eKey Mechanical \u0026amp; Installation Benefits:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul style=\"margin-top: 0; margin-bottom: 20px; padding-left: 20px;\"\u003e\n\u003cli style=\"margin-bottom: 10px;\"\u003e\n\u003cstrong\u003eIntegrated Auxiliary End Switch:\u003c\/strong\u003e Outfitted with a built-in micro-switch that registers complete physical port opening.
