Honeywell Home V4043H V4043H1106 28 mm 2 port zone valve 240V

This V4043H motorised two port zone valve with 28mm compression connections is suitable for a variety of flow control applications in domestic and light commercial central heating systems. Positioned where it cannot block any vent or cold feed when closed, this valve can be plumbed at any angle but the powerhead should not be below the horizontal level of the pipework. If fitted in a confined space, ventilation must be available to keep the valve within its ambient temperature range and access should be available for removing the powerhead if required
