La válvula mía tenía el mismo número pero el orificio inferior era mucho más pequeño que la que enviaron no se por que .

I retrofit this pressure sensor into my espresso maker to replace one just like it. For the most part it works great. A pressure plate rises and falls to activate a small microswitch to cut the boiler heater power. Once in a while, something goes awry and the switch does not activate and the pressure gauge goes off in the wrong direction causing the overpressure valve to kick in. As with any pressure vessel, its best to keep an eye on these things when they operate.These little pressure regulators fail when calcium builds up inside and prevents the little plate from moving freely. Decalcifying the pressure gauge will extend its life substantially. Also keep a supply of compatible micro switches on hand. These small switches can fail when controlling a high watt heating element due to internal arcing.

Looks like no one is selling a pressurestat for Pasquini livia 90s any more. Replaced mine with this part a month ago, and it’s working great.
