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.

■ Installation
he V4043 Zone Valve must be
T
positioned where it cannot block any
vent or cold feed when closed. It may
e plumbed in at any angle but must
b
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.
