Heating Controls - Multi-Port / Diverter Vlaves

Honeywell V4043 Motorised 2 Port Valve

The Honeywell range of 2 and 3 port spring return valves covers all the motorised valve requirements for domestic central heating plus many applications for commercial buildings. With all models it is possible to replace either the powerhead or the drive motor without the need to drain the heating.

The V4043H normally closed models have end switches for electrical control of boiler and pump. The normally open model is particularly applicable to the control of solid fuel systems, since it will open in the event of a power failure.

These valves are also suitable for use in light commercial applications. Valves are available in both 22 and 28mm compression fitting and 1/2", 3/4" and 1" BSP sizes.

All sizes of normally closed valve have a manual lever to facilitate filling and draining down and a 1 metre flying lead.

Myson - Motorised Mid Position / Diverter Valves

A motorised valve is used to control water flow from the boiler to heating and hot water circuits and is operated electrically.The Myson Powerextra motorised valve has been designed and developed with complete reliability and compatibility in mind – a culmination of years of developments both in design and production with rigid quality controls throughout. The new MPE 322 for example has a market-leading 6-watt class ‘F’ motor.

Two Port Myson – A two port motorised valve will control either the central heating or hot water circuit. Two ports can also be used to split the central heating system into several circuits to provide even better control. Please see Technical PDF file to explain further.

The MPE 322 + MPE 328 Three Port Mid position Valve will control both the central heating and hot water circuits simultaniously. Valve may be operated directly by the system programmer or via room and cylinder thermostats.

Three Port Myson – A three port motorised valve controls water flow to two destinations and may be either a diverter valve or a mid-position valve.
