Resideo - Honeywell Home V8043E1129 Motorized Zone Valve

The Motorized Zone Valve with the model V8043E1129 from Resideo–Honeywell Home delivers precise 2-way zoning control for hydronic heating systems. This normally closed, 2-position valve features a spring-return to close and opens in about 15 seconds, ensuring fast zoning response. With a 1/2 inch nominal size and inverted flare end connections, it fits standard piping. The brass body houses a stainless steel stem, EPDM packing, and Buna-N plug, delivering durable performance for hot water up to 200°F and up to 125 psi static pressure. Designed for low-voltage control, it draws 24 VAC at 0.32 A (roughly 7.7 VA) and includes an 18-inch lead and a manual opener for partial manual operation. UL-listed and suitable for hydronic control, this valve supports a flow coefficient (Cv) of 3.5 and is built for reliable, long-term operation in residential or light commercial systems.
