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
