Resideo V8043F1028 Valve

Resideo V8043F1028 Valve

When you need a reliable 2-way normally closed zone valve for hydronic heating systems, the Resideo V8043F1028 is a standard-setting component in the industry. Engineered for precision control, this 1/2 inch sweat zone valve utilizes a 24Vac motorized actuator and a high-performance spring return to close mechanism to ensure failsafe operation. Built with a rugged forged brass body and a corrosion-resistant stainless steel stem, it is designed to manage hot water flow in radiators, baseboards, and radiant coils with a 3.5 Cv flow capacity.

The motorized hydronic valve features a screwed terminal block for secure wiring and a manual opener for system filling or emergency bypass during power outages. With a maximum close-off pressure of 20 psi and a normally open auxiliary switch for burner or circulator control, the V8043F1028 ensures seamless integration into multi-zone residential or light commercial layouts. The compact screw terminal zone valve permits actuator replacement without breaking plumbing lines, reducing downtime and maintaining system integrity.

Key Benefits for Technicians:
  • Efficient Installation: The 1/2 inch sweat connection and screw terminal block simplify both the brazing process and electrical hookup.
  • Serviceability: The complete powerhead can be removed or the 24v actuator motor replaced without draining the hydronic loop.
  • System Security: The normally open end switch provides a reliable dry contact for triggering boiler firing and circulator pumps.
  • Manual Override: A dedicated manual lever allows for manual opening; the valve automatically resets to the closed position once power is restored.
Common Questions:

How do I wire the V8043F1028 aux switch?
Use the screw terminal block to connect your thermostat leads to the motor terminals. The normally open auxiliary switch (end switch) terminals are wired in parallel with other zone valves to the TT terminals on the boiler aquastat, ensuring the boiler fires only when a zone is fully open.

Can the V8043F1028 be used with chilled water?
This specific model is optimized for hydronic heating systems. Standard units are rated for fluid temperatures up to 200°F. For chilled water or cooling applications, specialized Resideo models with moisture-resistant actuators are recommended to prevent condensation damage.

What is the maximum differential pressure for this valve?
The Resideo V8043F1028 has a maximum close-off pressure of 20 psi. It is essential to size your circulator properly to ensure the spring return can effectively shut against the system's differential pressure.
