A synchronous motor for motorised valve systems, the Unvented Components Europe Synchronous Motor delivers steady, low-speed actuation suited to zone valves. Installers and maintenance engineers gain confidence from a direct-replacement design that reduces downtime. Is compatibility with Honeywell parts and straightforward installation enough for most retrofit jobs?
⚡ At a Glance
- • Rotation Speed: 5 RPM at 220V 50Hz for steady, low-speed actuation
- • Best for: Plumbers and HVAC technicians replacing Honeywell V4043H zone valve motors
- • Not ideal for: Applications requiring variable-speed control or high-torque actuators
Designed as a direct replacement for Honeywell 40002737-003 and compatible with V4043H zone valve systems. Operates on a 220V 50Hz supply and runs at a steady 5RPM for predictable valve movement.
Consistent valve timing - with synchronous 5RPM rotation
A synchronous motor locks rotational speed to the AC line frequency, delivering a fixed 5 revolutions per minute at 220V 50Hz. The steady speed avoids variations common to asynchronous motors.
Predictable movement ensures valves open and close at consistent rates, helping maintain stable zoning and timing in heating systems.
Quick swap installation - thanks to pre-wired connections and included mounting hardware
Pre-wired terminals match common Honeywell motor connections and supplied mounting hardware aligns with typical valve bodies for a direct fit. No custom wiring or fabrication is required for most replacements.
Replacement jobs finish faster with less on-site labour, reducing downtime and simplifying routine maintenance visits.
Built for long service - with durable metal housing and robust internals
A metal housing protects moving parts and internal components from mechanical wear and environmental exposure, while the synchronous design places less stress on speed control systems.
Fewer premature failures and reduced call-backs result from the robust construction, making the unit a dependable option for busy plant rooms.
