Description
The Honeywell/Resideo V4043B1018 is a premium two-way line-voltage zone valve engineered for hydronic HVAC systems. Featuring a ½″ sweat connection and a durable brass body, this motorized valve enables smooth control of hot or chilled water flow with a reliable normally-open configuration—closing only when energized. It’s designed for efficient zoning in boilers, radiant loops, fan coils, and more.
