V3474 Communication Cable 8ft for V3030-01 Clack System Controller Clack

This is the genuine Clack V3474 communication cable, an 8ft lead used to link a Clack control valve to a V3030-01 system controller on installations where the two units are mounted close together. WrekinWater supplies this cable individually for customers whose original lead has failed or been damaged during servicing. It uses the same plug connections as the factory-fitted cable, so it's a direct swap.

Signs you need this part

• The V3030-01 controller shows a communication or connection error with the valve.
• The cable insulation is cracked, kinked sharply or partly cut through.
• A plug connector is loose, bent, or no longer seats securely at either end.
• The valve stops responding to controller commands despite power being present.

This short cable is what allows the V3030-01 controller to actually talk to the control valve, so any fault in the wire or its connectors breaks that link even though both units may be functioning correctly on their own. Because it's often routed in tight spaces close to the valve body, it can get pinched, trapped or flexed repeatedly during servicing, which weakens the conductors inside over time. When it fails, the system can appear unresponsive or throw a fault code that has nothing to do with the valve mechanism itself.

WrekinWater is a family run company operating from Bettisfield, Shropshire, that has served more than 50,000 customers over 15 years and stocks genuine Clack cables rather than unbranded alternatives. The correct manufacturer cable guarantees the right pin-out and plug fit for your V3030-01 controller, with support from a UK team (Company No. 11000488) rated Excellent on Trustpilot.

How to fit it

1. Isolate power to the control valve and system controller before disconnecting any cabling.
2. Note the port each end of the existing cable connects to.
3. Unplug the damaged cable from the valve and the V3030-01 controller.
4. Fit the new cable along the same short run, keeping it clear of any moving parts.
5. Plug both ends in firmly until they click or seat fully.
6. Restore power and check the controller registers the valve correctly.
