Expansion valve 38m14m 10060460

What is an expansion valve and what is it for

The expansion valve is a safety component in the coffee machine's boiler circuit. Its role is to keep the pressure within safe limits and, if it is exceeded, to release the excess pressure, thereby protecting the boiler and other components from damage.

Signs of wear or malfunction

A worn or clogged valve can manifest itself through dripping or leaking water or steam even outside normal operation, fluctuating pressure in the boiler, unusual hissing, or, conversely, by not opening at all, leading to a dangerous rise in pressure.

When it's time for a replacement

A functional expansion valve is essential for the safe operation of the coffee machine. Its wear affects not only the comfort of use but above all the safety of the machine, so replacement should not be delayed at the first signs of leakage or malfunction.
