Taco Zone Sentry 3/4" Normally Open Zone Valve

The Taco Comfort Solutions V075C2A3 Zone Sentry® Motorized Zone Valve provides high-efficiency, bi-directional fluid control for modern multi-zone hydronic heating and cooling systems. Featuring a heavy brass 3/4" sweat connection body paired with an advanced, microcircuit-controlled motorized actuator head, this model is configured as a Normally Open (N/O) assembly. The valve remains resting in a fully open position under zero electrical load, offering an essential mechanical safe-state for radiant loops, baseline bypass circuits, or extreme climate freeze-protection architectures.

Key Mechanical & System Benefits:

• High close-off Pressure Rating: Built with a high-torque commercial ball-valve core providing up to 125 PSI of definitive close-off pressure capacity, entirely preventing velocity whistling, water hammer noise, or localized seat weeping.
• Patented Toolless Quick-Release: Features a rugged snap-lock push button allowing the entire green actuator control block to be detached from the solid brass fluid body in seconds. Maintenance teams can swap heads without interrupting the hydronic line or draining system glycol.
• Unrivaled Green Energy Savings: Employs high-efficiency microcircuit gear tracking that draws a minimal 1.44 Watts only during active transit cycles. This allows up to 12 separate Zone Sentry valves to run simultaneously off a standard 40VA multi-zone transformer.

Auxiliary Integration: Comes outfitted with an integrated micro-switch end contact loop to signal zone relays, boiler control terminals, or distribution circulators the moment the mechanical cycle completes.
