Resideo - Honeywell Home V4043E1003 Motorized Zone Valve

The V4043E1003 Motorized Zone Valve from Resideo—Honeywell Home delivers precise hydronic control for heating systems. This 2-way, straight-through valve uses a 1/2 inch nominal size with soldered x soldered end connections and offers a 2-position, spring-return actuation. The valve is normally closed, providing reliable shutoff when power is removed, and it's built with a brass body, stainless steel stem, EPDM packing, and Buna-N ball plug for dependable service with low-pressure steam. With a 15-second opening time, line voltage operation, and an 18-inch electrical lead, it fits a wide range of installations. Rated for temperatures from 40 to 240 degrees F and compatible with static pressures up to 125 psi (steam at 15 psi), this valve is UL and CSA listed for safe, compliant performance in hydronic heating systems. Its compact footprint (3-1/2" W x 2-3/8" D x 4" H) and 3.5 Cv flow capacity ensure steady, balanced flow in retrofit projects and new builds.
