The Taco Zone Sentry Replacement Actuator Head (MPN: ZA024Q4A2) is a high-performance, motorized solid-state control module engineered to snap directly onto existing Taco Zone Sentry, EBV, or ESP series zone valve bodies.

Advanced Close-Off & Efficiency Engine:

  • Extreme 125 PSI Shut-Off Control: Features an optimized, high-torque microcircuit-driven gear motor that ensures absolute shut-off integrity up to 125 PSI, preventing weeping or system bleed-through in residential and commercial circuits.
  • 93% Energy Reduction: Utilizing a patented Prostar capacitor charging setup, it draws an ultra-low 1.44 Watts only when cycling, allowing you to run up to 12 actuator heads simultaneously on a single 40VA multi-zone transformer.
  • Tool-Free Fast Installation: Designed with a quick-release mounting clip to snap securely into place over the valve body in seconds, eliminating the need to isolate, open, or drain the system fluid loop during replacement.

Diagnostic Integration:

  • Multi-Function LED Status Light: Built-in green LED diagnostic indicator immediately alerts field technicians to thermostat status and actuator health to simplify hydronic system troubleshooting.
