The Taco 570 Series Gold Motorized Hydronic Zone Valve is a high-performance zone valve engineered to deliver premium hydronic efficiency and reliability. 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.
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.
Advanced Engineering Features:
- Iconic Gold Heat-Motor Design: Silent thermostatic expansion operator mechanism eliminates the loud water hammer and gear stripping common in motorized zone valves.
- Toolless Twist-Lock Assembly: Actuator head separates from the brass body with a simple twist, allowing rapid service upgrades without draining down the hydronic lines.
- Built-In Auxiliary End Switch: Low-voltage end-switch isolates zones completely, preventing ghost flows and back-pressures across manifold links.
