Resideo - Honeywell Home V8043E1020 Motorized Zone Valve

The V8043E1020 motorized zone valve from Resideo - Honeywell Home delivers precise, energy-efficient control for hot water hydronic systems. This motorized zone valve is a 2-Way, straight-through design with a 1" nominal size and soldered x soldered end connections, built around a durable brass body with a stainless steel stem, EPDM packing, and Buna-N ball for long service life.

With 2-position actuation and spring return to close, the valve is normally closed to provide fail-safe zoning. The 15-second valve timing to open ensures quick zone activation, while the 18" electrical lead and SPST end switch support simple low-voltage integration. It operates on 24 VAC (7.7 VA, 0.32 A).

Designed for hot water media, it handles fluids from 50 to 200°F and tolerates up to 125 psi static (20 psi close-off). This UL and CSA listed valve is suitable for residential or light commercial hydronic control, with ambient ratings up to 125°F and non-condensing humidity of 5–95%.
