Product Information
Full details
The Banico H-ZVM 3-Port Motorised Zone Valve Head is designed for homeowners and DIY enthusiasts looking to repair their domestic central heating system's hot water flow control. Its key benefit is the ability to replace a failed actuator without draining the entire system, saving time and effort. A potential caveat is that it's only compatible with 3-port (mid-position) valves and requires basic electrical knowledge for installation. This unit acts as a replacement actuator for Banico 3-port mid-position zone valves, controlling the flow of hot water between your heating circuit and hot water cylinder.

FAQs
Do I need to drain my heating system to fit this valve head?
No, one of the main benefits of the Banico H-ZVM is that it is designed to be replaced without draining the central heating system.
What type of zone valve does this head fit?
This H-ZVM valve head is specifically designed for 3-port (mid-position) zone valves.
What sizes of valve bodies does it fit?
It fits 3-port mid-position valve bodies with connections of 22mm, 28mm, ¾”, and 1″.
What voltage does the Banico H-ZVM operate on?
The unit operates on a standard 230V AC power supply.
Can I use this to replace a 2-port zone valve actuator?
No, this H-ZVM is only compatible with 3-port (mid-position) zone valves. A different model would be required for a 2-port valve.
How do I know if my actuator needs replacing?
Common signs include the heating or hot water not coming on when called for by the thermostat, or the valve head making persistent clicking or grinding noises.
Is this a complete zone valve or just the head?
This product is a replacement actuator head only. It is designed to fit onto an existing, serviceable valve body.
Troubleshooting
Zone valve head does not move when system is on.
Ensure the power supply to the valve is correctly connected and the 230V AC supply is live. Check the wiring connections against your system's diagram. If power is present and the unit is still unresponsive, the actuator may be faulty.
Heating or hot water not working after installation.
Double-check all wiring connections are correct and secure according to your system's wiring plan. Verify that the thermostat is calling for heat or hot water. Ensure the valve head is properly seated on the valve body.
Valve head makes unusual noises.
A slight humming noise during operation is normal for some motorized valves. However, loud grinding or clicking may indicate an obstruction or a failing actuator. Ensure the valve is not being forced against its end stops.
Water leaking from the valve area.
The H-ZVM head itself should not leak water. If you observe a leak, it is likely coming from the valve body seals or pipe connections. The valve body may need servicing or replacement, which would require draining the system.

Setup, Compatibility & Care Instructions
Compatibility:
- This H-ZVM valve head is designed exclusively for 3-port (mid-position) zone valves. Ensure your existing valve body is a 3-port type.
- It fits valve bodies with standard connections of 22mm, 28mm, ¾”, and 1″.

Setup (Installation):
- Safety First: Turn off the power to your central heating system at the main isolator switch.
- Remove Old Head: Unscrew or unclip the existing valve actuator head from the valve body.
- Mount New Head: Align the H-ZVM head with the valve body and secure it (usually with a screw or clip, depending on the original fitting).
- Connect Wiring: Connect the wires from your central heating system's wiring center to the corresponding terminals on the H-ZVM head. Refer to your system's wiring diagram for correct connections. *If unsure, consult a qualified professional.*
- Restore Power: Turn the power back on to the central heating system.
- Test: Check that your heating and hot water operate correctly.
Care:
- The H-ZVM head is a sealed electrical unit and requires minimal user care.
- Keep the area around the valve clear of dust and debris.
- Do not attempt to open the unit for cleaning.
- Periodically check that the wiring connections remain secure.
