Honeywell V8043F1036 Zone Valve – 3/4" Sweat, Two-Way On/Off Control with End Switch
The Honeywell V8043F1036 is a low-voltage, motorized zone valve designed for hydronic heating systems requiring on/off flow control. This model features a 3/4" sweat connection and includes an integral end switch, allowing for coordination with other system components such as circulators or burners.
Product Overview
- Function: Two-way, straight-through valve; opens on power and spring-returns closed when de-energized
- End Switch: Provides auxiliary control signal when valve reaches full open position
- Manual Lever: Integrated lever for system fill or manual operation during power loss
- Application: Designed for closed-loop hydronic systems in zoning applications
Key Features
- Connection Type: 3/4" sweat fittings for copper tubing
- Flow Coefficient (Cv): Rated at 3.5 Cv
- Electrical Interface: Screw terminal block for secure 24V AC connections
- Replaceable Powerhead: Field-replaceable actuator without draining the system
- Actuation Time: Approximately 15 seconds powered; spring-return on power loss
Technical Specifications
- Voltage: 24V AC, 50/60 Hz
- Max Fluid Temp: 200°F (93°C)
- Max Close-Off Pressure: 20 PSI
- Body Pattern: Straight-through
- End Switch Rating: 50 VA pilot duty @ 24V AC
Installation and Application Notes
This valve is intended for installation in the return piping of a closed hydronic loop. It should be mounted with the actuator in a horizontal position to prevent motor damage from condensation. Electrical connections should be made in accordance with NEC and local code requirements. The V8043F1036 is suitable for integration with thermostat-controlled zoning systems using a 24V transformer and compatible relay or zone panel.
Contractor Considerations
- Pre-stripped screw terminals simplify field wiring
- End switch facilitates burner or pump interlock
- Manual opener enables system servicing without energizing the valve
- Common choice for retrofit and new installations in zoned hot water systems
