What it is

The Hamworthy 531911036 is a wafer-pattern butterfly valve used on Hamworthy floor-standing gas boilers. It sits between two pipe flanges to provide isolation and flow control on the water circuit. Manufacturer reference K94049.

Signs this part needs replacing

  • Water weeping from the valve body, spindle or flange faces
  • The valve no longer isolates the circuit when closed
  • Stiff, seized or broken operating handle
  • Visible corrosion, scale or debris around the disc or seat
  • Poor flow control or restricted flow through the valve

Before you order

  • Confirm the boiler model against the fit list above
  • Check the existing valve is a wafer-pattern type and matches the pipework
  • Verify part number 531911036 or reference K94049 on the old component
  • Isolate and drain the relevant section of the system before removal
