Resideo - Honeywell Home VU843A1004 Valve Actuator

The Valve Actuator from Resideo - Honeywell Home VU843A1004 delivers precise control for HVAC equipment. This SPST, 2-position actuator uses spring-return action and a lever for reliable, fail-safe damper and valve operation across commercial HVAC applications.

Designed for 24V AC systems, it runs at 50/60 Hz with a driving power of 6 Watts. The stainless steel body provides durability in demanding environments, while a compact footprint (3-1/2 in. wide by 2-3/8 in. high) and a 6-inch wire lead simplify installation. With a 22-degree rotation and an ambient operating range of 34 to 125°F, this actuator is suitable for HVAC equipment such as fan coils, reheat coils, and convectors. It’s CSA approved for added safety in professional installations, and offers reliable timing of 4 seconds to ensure consistent valve actuation.
