Resideo - Honeywell Home V8043E5020 Motorized Zone Valve

The V8043E5020 Motorized Zone Valve from Resideo/Honeywell Home is a 1-inch, 2-way zone valve designed for reliable hydronic control. With soldered x soldered end connections and a brass body, it delivers durable performance for hot-water systems in residential and light commercial settings.

This 2-position valve features a spring-return to close and is normally closed, providing immediate shutoff when power is removed. A fast 15-second open time ensures responsive zoning, while the 24 VAC control (0.32 A, 7.2 VA) supports low-voltage operation. The valve is rated for fluid temperatures from 50 to 200 F and pressures up to 20 psi close-off and 300 psi static, making it suitable for everyday hydronic installations.

CSA-approved and built for hydronic control, the V8043E5020 includes a manual opener and an SPST end switch for straightforward integration into existing systems. Its compact enclosure measures 3-1/2 in W x 2-3/8 in D x 4-3/8 in H and uses an 18-inch electrical lead.
