Glow-worm Xtramax 96 Boiler Pressure Relief Valve PRV 05722800 57228
Product Overview
The Glow-worm Xtramax Boiler Pressure Relief Valve (PRV) (Part Numbers: 05722800 / 57228) is a replacement safety component designed for selected Glow-worm heating systems.
Part number 57228 is identified in the manufacturer's technical documentation as a Central Heating Safety Valve.
The Pressure Relief Valve forms part of the boiler's sealed central heating circuit, protecting the system against excessive pressure by allowing water to discharge when the specified pressure limit is reached.
Correct operation of this safety component is important for maintaining safe pressure conditions within the heating system.
ℹ️ Product Condition Options:
This part may be available in New or Refurbished condition. Please select your desired option from the dropdown menu above. Any refurbished safety valve must be professionally assessed and tested to confirm that it meets the required operating specifications before installation.
Technical Insight & Common Failure Symptoms
The Pressure Relief Valve is a mechanical safety device designed to protect the boiler's central heating circuit against excessive pressure.
Under normal operating conditions, the valve remains closed. If system pressure exceeds its specified relief setting, the valve opens to discharge water through the safety discharge pipe.
Over time, the valve may experience sealing deterioration, internal contamination or wear, particularly following repeated operation.
Possible symptoms that may indicate a Pressure Relief Valve or associated system problem include:
-
Water dripping or discharging from the pressure relief pipe.
-
Boiler pressure dropping after water has been discharged.
-
Continuous leakage from the valve outlet.
-
Pressure Relief Valve failing to reseal correctly.
-
Repeated discharge caused by excessive system pressure.
-
Difficulty maintaining normal central heating system pressure.
-
Visible corrosion, damage or deterioration around the valve.
These symptoms do not necessarily confirm a faulty Pressure Relief Valve, as similar problems may result from expansion vessel faults, excessive filling pressure or other heating system components. Correct professional diagnosis should be carried out before replacement.
Compatibility
This part (MPN: 05722800 / 57228) is identified for selected Glow-worm Xtramax boiler systems, including the Xtramax 96.
Please verify the boiler model, part number, valve pressure rating and connection arrangement against the manufacturer's technical documentation before ordering to ensure correct fitment.
Safety Advice
Boiler Pressure Relief Valves are safety-critical components within a pressurised heating system and should only be inspected, removed or installed by a suitably qualified and competent heating engineer.
Always isolate the appliance and allow the heating system to cool before carrying out any work. The system must be safely depressurised in accordance with the manufacturer's servicing instructions. Never block or restrict the safety discharge pipe. The correct valve pressure rating must be maintained, and appropriate pressure, leakage and operational safety checks must be completed before the boiler is returned to service.
