What it is
The SATKF2044 is a differential pressure control valve (DPCV) for Caleffi HIU heat interface units. It regulates the differential pressure across the HIU circuit so flow conditions stay stable as demand changes. It is listed as a service component within the Caleffi HIU product range.
Signs this part needs replacing
- Differential pressure drifting from the set value, giving unstable DHW or heating temperatures
- Audible noise or vibration from the valve during operation
- Water weeping from the valve body or its connections
- Poor response to changes in demand across the HIU circuit
- Pressure fluctuations at the HIU where the valve no longer holds control
Before you order
- Confirm the part number SATKF2044 matches the valve fitted to your unit.
- Check your HIU model against the manufacturer's parts list to confirm compatibility.
- Isolate and depressurise the HIU before removing or fitting the valve.
- Fitting should be carried out by a competent heating engineer.
