Pressure relief valve from production 1938

What this valve does

The pressure relief valve from production 1938 is a safety component that releases excess pressure from the coffee machine's boiler or brewing circuit. It keeps internal pressure within safe operating limits, protecting the machine from damage and the user from unsafe operation.

Signs it needs replacing

Over time a pressure relief valve can wear out due to constant heat and pressure cycles. Signs of a failing valve include hissing or leaking noises, difficulty building or maintaining pressure, or the machine failing to reach proper brewing pressure at all. A valve that no longer seats correctly should be replaced promptly to keep the machine safe and functioning properly.
