What it is
The Honeywell V7335A is a modulating gas pressure regulator, commonly known as a modureg, used on Sime gas boilers. It varies burner gas pressure in response to the modulating signal from the boiler control, allowing the appliance to match heat output to demand. Sime lists this component under part number 6242404.
Signs this part needs replacing
- Burner pressure does not vary with demand and stays fixed at minimum or maximum
- Boiler cycles or hunts instead of modulating smoothly
- Flame instability, weak flame or repeated ignition faults
- Domestic hot water temperature fluctuates despite steady demand
- Gas pressure readings at the burner fall outside the values given in the appliance instructions
Before you order
- Confirm your appliance model against the fit list above, as the same boiler family can use different gas valves
- Check the part number marked on the existing modureg before ordering
- Verify the fault is with the regulator and not with the modulating signal from the boiler control board
- Work on gas-carrying components must be carried out by a Gas Safe registered engineer
