Description
If you’re servicing hydronic HVAC systems and you need a reliable zone valve actuator, the 23B0012N13 is a genuine OEM unit designed for precision control. Compatible with many zone valves in 24 V systems, this normally-closed (NC) actuator features an integrated end switch so you can monitor when the valve reaches its fully open or closed position. Engineered for long performance and drop-in replacement, it makes servicing simpler and supports system reliability.
Key Features
- 24-Volt Operation: Designed for standard low-voltage HVAC control systems, simplifying integration into existing setups.
- Normally Closed Configuration: Valve remains closed when de-energized, which provides fail-safe behavior when control power is lost.
- Built-in End Switch: Provides feedback of valve position (open/closed), enabling enhanced system diagnostics and automation compatibility.
- OEM Quality Replacement: Trusted brand and original part number ensure compatibility, fit and performance equivalence with original system components.
- Compact & Durable: With a light weight (~0.59 lb) and standard mounting dimensions, it simplifies installation in tight spaces.
