Description
Honeywell 40003916-013 Replacement Zone Valve Actuator
The Honeywell 40003916-013 is a direct replacement actuator engineered for reliable zone valve operation in hydronic heating and cooling systems. Designed for 24-volt normally closed (NC) applications, this actuator opens the valve upon power application and returns to the closed position when de-energized — providing fail-safe performance in the event of a power interruption.
Key Features
- Direct replacement actuator for compatible Honeywell zone valves
- 24V AC operating voltage for standard low-voltage hydronic control systems
- Normally Closed (NC) operation — valve closes automatically on power loss
- Integrated end switch for auxiliary control and system feedback
- Convenient screw terminal wiring connections for fast, secure installation
- Designed for straightforward field replacement without full valve body removal
Application
Ideal for residential and light commercial hydronic zoning systems, this replacement actuator restores proper zone valve function quickly and cost-effectively. The screw terminal design simplifies wiring during service calls, reducing installation time and minimizing the risk of loose connections. The built-in end switch enables downstream control actions such as circulator pump activation or boiler sequencing.
Why Choose the Honeywell 40003916-013
- OEM-quality replacement extends the life of existing zone valve bodies
- Normally closed fail-safe design protects the system during power outages
- End switch supports multi-zone system integration
- Screw terminals provide reliable, vibration-resistant connections
