Resideo - Honeywell Home V4043A1705 Motorized Zone Valve

The Motorized Zone Valve from Resideo - Honeywell Home V4043A1705 delivers precise hydronic control for heating and cooling systems. This 2-Way, straight‑through valve uses a 3/4 inch nominal size with threaded end connections and a brass body for durable, long‑lasting performance.

Designed for hot and chilled water, it opens quickly in about 15 seconds and uses a 2‑Position, spring return mechanism to close. The valve is normally closed, ensuring a fail‑safe shutoff when power is removed. It features an 18‑inch lead electrical connection and supports line voltage operation, making it compatible with typical heating circuits.
