The Taco Comfort Solutions Z075C2-1 Zone Sentry® Motorized Zone Valve sets the modern standard for energy-efficient, high-performance flow control in multi-zone hydronic heating and cooling systems. Utilizing a commercial-grade brass body with 3/4" sweat (solder) connections, this valve is configured in the industry-standard Normally Closed (N/C) position. Driven by an advanced microcircuit-controlled gear actuator, the valve opens smoothly when energized and provides a bubble-tight seal when closed, preventing ghost flows and temperature bleed across inactive zones.
Key Performance & Installation Advantages:
- Unmatched Close-Off Pressure: Engineered with a high-torque internal ball-valve mechanism rated for up to 125 PSI of definitive shut-off pressure. This design completely eliminates water hammer, velocity whistling, and seat weeping common in older paddle-style zone valves.
- Maximum Electrical Efficiency: High-efficiency microcircuitry draws a mere 1.44 Watts of power only while moving. Because it uses up to 70% less energy than standard thermal-motor valves, you can safely power up to 12 Zone Sentry units off a single 40VA multi-zone transformer.
- Toolless Push-Button Release: The distinctive green actuator head features a patented quick-release snap lock. Service technicians can replace or service the control head in seconds without breaking solder joints or draining water/glycol from the loop.
System Capabilities: Includes an integrated auxiliary dry-contact end switch to instantly activate system circulators or signal boiler controls the moment the valve reaches its fully open position.
