Honeywell Home 28mm Motorised 3 Port Mid-Position Valve | V4073A1088/U Y-Plan Diverter Valve
Honeywell Home 28mm Motorised 3 Port Mid-Position Valve | V4073A1088/U Y-Plan Diverter Valve
The Honeywell Home V4073A1088/U is a 28 mm 3 port mid-position motorised diverter valve for fully pumped conventional central heating systems controlling both radiator and hot water cylinder circuits. Designed for small to medium installations, it works with room and cylinder thermostats in Sundial Y-plan configurations.
Key Features
- 3-position operation: Port A (heating), Port B (hot water), Port AB (mid-position for simultaneous flow).
- Spring return action prioritises hot water on power failure for safety.
- Powerhead replaceable without draining the complete heating system.
- Manual lever for easy system filling and draining in MAN OPEN position.
- Electrical output controls boiler and pump operation automatically.
- Quiet operation, minimal 6 W power consumption suitable for domestic use.
Why Choose Honeywell Home V4073A1088/U?
Proven industry standard for Y-plan fully pumped heating systems, offering reliable diverter operation with service-friendly design and comprehensive electrical interlock.
Handles systems up to 90,000 BTU (26 kW) capacity with robust brass construction for long service life.
Suitable For
- Sundial Y-plan installations with independent heating/hot water temperature control.
- Medium-sized domestic heating systems with 28 mm primary pipework.
- Conventional fully pumped boilers requiring precise flow diversion.
