The Vaillant Pressure Relief Valve Set GB 0020094185 is a heating system spare part designed to help manage excess pressure within a compatible central heating system. The valve opens proportionally as pressure increases, helping prevent pressure from reaching dangerously high levels and supporting the safe operation of the heating system.

Designed for compatible Vaillant heating equipment, this pressure relief valve is suitable for relevant boiler maintenance and repair applications. Correct replacement of the valve can help restore the intended pressure-relief function when an existing component is faulty or requires servicing.

This set includes a washer and O-ring to support installation. Before ordering, check the manufacturer part number and confirm compatibility with your specific Vaillant boiler model.
