What it is

The Altecnic SATKF0039 is a 1.65 bar rated control valve obturator for Caleffi HIU products. It functions as a two-way modulating valve and diverting valve within the unit. The obturator is the moving element that regulates flow through the valve body.

Signs this part needs replacing

  • Domestic hot water temperature no longer holds steady, indicating the valve is not modulating correctly.
  • The valve sticks or fails to move through its full travel.
  • Scale or debris build-up on the obturator causes erratic flow control.
  • Water weeping from the valve area around the obturator.
  • The unit fails to divert correctly between heating and hot water modes.

Before you order

  • Confirm your appliance is a Caleffi HIU product and check the model against the manufacturer's parts list.
  • Verify the existing valve is rated at 1.65 bar.
  • Confirm the valve function required is two-way modulating or diverting.
  • Check whether the obturator alone is required or whether the complete valve assembly is being replaced.
