APPLICATION
The V4043 series of two port Motorised Valves 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 and/or boiler. The V4043B normally
open model is particularly applicable to control of solid fuel
systems, since it will always fail-safe in the event of a
power failure.
