What it is
The Caleffi HIU heating valve body and cartridge is an on/off complete assembly used within Caleffi HIU (heat interface unit) products. It controls the flow of heating water through the unit, opening and closing the heating circuit on demand. The assembly is supplied as a body with its cartridge fitted, so the flow control element is replaced as one unit.
Signs this part needs replacing
- Heating demand is not met, with the valve failing to open when the unit calls for heat
- Heating water continues to pass through the circuit when the valve should be closed
- The valve sticks or responds slowly, causing erratic or delayed heating output
- Water weeping from the valve body or around the cartridge spindle
- Debris or scale in the cartridge causing poor or inconsistent flow control
Before you order
- Confirm your appliance is a Caleffi HIU product and check the model against the manufacturer's parts list
- Verify the part number SATKF0031 matches the valve currently fitted
- Check whether the full body and cartridge assembly is required rather than the cartridge alone
- Isolate and drain the relevant circuit before removal and fitting
