What it is

The Hamworthy 339012158 is a 1" BSPT female-to-female gas isolation ball valve used on Hamworthy floor-standing boilers. It provides a quarter-turn shut-off point on the gas supply so the appliance can be isolated for servicing or repair. It is listed for use across the Modumax, Purwell and Warmwell ranges.

Signs this part needs replacing

  • The valve handle is stiff, seized or will not turn through its full quarter-turn.
  • The valve no longer shuts off the gas supply completely when closed.
  • A smell of gas, or a leak detected at the valve body, spindle or threaded connections.
  • Corrosion, staining or weeping around the valve body or spindle.
  • The handle turns freely without operating the valve internally.

Before you order

  • Confirm the existing valve is 1" BSPT female-to-female; thread size and gender must match.
  • Check the appliance model against the fit list above.
  • Confirm the number 339012158 matches the existing valve or the manufacturer's parts list.
  • Gas work must be carried out by a competent, Gas Safe registered engineer, with the supply isolated and the joint leak-tested after fitting.
