What it is

This is a gas valve manufactured by Honeywell for Sime gas boilers. It is identified by Sime part number 6243821 and Honeywell model VK115V1006 (also referenced as VK4115V). The valve controls the flow of gas to the burner in Sime Format and Dewy Zip series appliances.

Signs this part needs replacing

  • Boiler fails to ignite or fires intermittently.
  • No gas flow to the burner despite a call for heat.
  • Error code indicating a gas valve fault.
  • Visible damage or corrosion on the valve body.
  • Gas smell near the valve (isolate gas supply and seek professional help).

Before you order

  • Check your boiler's model and gas type (natural gas or LPG) against the fit list.
  • Confirm the existing valve's model number matches VK115V1006 or VK4115V.
  • Verify the Sime part number 6243821 is correct for your appliance.
  • Ensure the boiler is isolated from the gas supply before fitting.
