Honeywell V8043E1012/U Zone Valve – Two-Way Low Voltage Control for Hydronic Systems
The Honeywell V8043E1012/U is a two-way on/off zone valve designed for hydronic heating systems requiring precise control of water flow. Operating on 24 VAC, this low voltage valve provides dependable isolation of individual zones in hot water heating applications. The motorized actuator controls the valve position based on external thermostat signals.
System and Application Use
- Valve Type: Two-way, normally closed, spring return
- Control Signal: Operates on 24 VAC from a low-voltage thermostat or controller
- Operation: Opens fully in response to thermostat demand; spring returns to closed position when power is removed
- End Switch: Integral end switch rated for 50 VA at 24 VAC for control of circulator or boiler
- Connection: 1/2″ sweat connections for copper tubing
Key Features
- Motor-Driven Actuation: Provides positive valve positioning with spring return fail-safe
- Replaceable Powerhead: Allows servicing without draining the system
- Built-In End Switch: Enables coordinated control with system pump or burner
- Application: Suitable for zoning in closed-loop hot water systems
- Rated Voltage: 24 VAC, 60 Hz
Technical Specifications
- Model Number: V8043E1012/U
- Line Size: 1/2 in. sweat connection
- Voltage: 24 VAC, 60 Hz
