A reliable 22 mm motorised 2‑port zone valve designed for Honeywell V4043 boiler heating systems. This premium‑quality, spring‑return valve comes with built‑in 22 mm compression fittings and an auxiliary switch, making it ideal for general‑purpose flow control in central‑heating or hot‑water circuits.
When wired to a room thermostat, cylinder thermostat and programmer, the valve automatically directs water from the boiler to either the heating loop or the hot‑water tank. The synchronous motor drive provides smooth operation while the spring‑return mechanism guarantees safe closure if power is lost.
