Resideo V4043A1705 Zone Valve
The Resideo V4043A1705 Zone Valve is a heavy-duty 120V motorized valve designed for precision control of hydronic systems. Featuring a 3/4" NPT connection and a Normally Closed (NC) configuration, this unit utilizes a spring return mechanism to ensure positive closure during power loss. With a 3.5 Cv flow capacity and a 20 PSI maximum close-off pressure, it is engineered for standard residential and light commercial boiler loops. The brass body, stainless steel stem, and EPDM rubber O-ring construction provide durability against fluid temperatures ranging from 40 to 200 degrees Fahrenheit. The manual opener lever allows for system filling and drainage without powering the actuator, while the 18-inch lead wires simplify HVAC zone valve wiring in tight mechanical rooms. This Resideo V4043 hydronic valve serves as a reliable replacement zone valve actuator and body assembly for maintaining balanced thermal distribution.
Key Benefits
- Reduced Mechanical Wear: The Buna-N rubber ball plug ensures a tight seal and resists debris buildup common in older hydronic loops.
- Serviceability: The manual lever allows technicians to manually lock the valve in the open position for rapid system air purging.
- High Thermal Tolerance: Rated for fluid temperatures up to 200°F, making it compatible with high-temperature baseboard and radiator systems.
- Simplified Integration: Standard 3/4 inch NPT threaded ports allow for direct installation without specialized adapters or custom manifolds.
Common Questions
Can the V4043A1705 be installed horizontally?
Yes, this valve can be mounted in horizontal or vertical piping, but the actuator head must remain above the center line of the pipe to prevent moisture damage to the motor.
Does this model include an end switch?
The V4043A models are typically two-wire valves without an auxiliary end switch; if your system requires a boiler start signal from the valve, verify your wiring schematic before installation.
Will this valve work with 24V thermostats?
No, the V4043A1705 is a 120Vac zone valve and requires a line-voltage power supply or a dedicated relay for operation.
