The Honeywell 22mm Motorised Zone Valve is a normally closed two-port motorised zone valve, with end switch for electrical control of pump and/or boiler, Ø22mm compression connections.
The V4043 series of two port Motorised Valves, as seen in this particular Honeywell zone valve, has a wide range of flow control applications in domestic and light commercial central heating systems. The V4043H normally closed models have end switches for electrical control of pump.
The Honywell Motorised 2-way Zone Valve controls the flow of water in a wide range of central heating systems and is used in conjunction with a room thermostat and cylinder thermostat to give control of water and radiators.
All sizes of normally closed valve have a manual lever to facilitate filling and draining down and a 1 metre flying lead.
Our range of two and three port Honeywell zone valves is the premier valve used in the domestic central heating industry, as a flow control mechanism in domestic and light commercial heating systems.
The Honeywell V4043H1056 22mm Motorised Zone Valve features:
- Motor open.
- Spring return action.
- Manual lever for filling & draining the system.
- Powerhead replaceable without draining down.
- Potential free end switch for electrical control of pump and/or boiler.
- Quiet operation, minimal power consumption.
Installation - The Honeywell V4043 Zone Valve must be positioned where it cannot block any vent or cold feed when closed. It may be plumbed in at any angle but must not be mounted so that the powerhead is below the horizontal level of the pipework. If fitted in a confined space, sufficient ventilation must be available to keep the valve within its ambient temperature range and access must be provided to remove the powerhead if necessary.
