Honeywell V4043 is a motorized zone valve designed for domestic and light commercial central heating systems, offering precise flow control. Its key features include:
- Motorized operation: Allows for automated control of hot water flow.
- Spring return action: Ensures valve closure in case of power loss.
- Manual lever: Facilitates manual filling and draining of the system.
- Replaceable powerhead: Enables easy maintenance without draining the system.
- Potential-free end switch: Provides electrical control of pumps and boilers.
- Quiet operation and low power consumption: Ensures energy efficiency.

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.

MOTORISED ZONE VALVES V4043B/C/H
■ Installation
T
he V4043 Zone Valve must be
positioned where it cannot block any
vent or cold feed when closed. It may
b
e 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.
