DISCONTINUED Sirai P302 30A Pressurestat / Pressure Switch
Please visit one of the links below for more comparable products.
This Sirai (pronounced “SUH-RYE”) pressurstat (pressurestat), also known as a pressure switch can be used on most commercial espresso machines with one, two or three groupheads. There are three sets of internal electrical contacts. Can be used for 110 volt, 208 volt, 220 volt, 230 volt, 240 volt, and 400 volt AC.
Some machines require a slightly smaller than full sized pressurestat for prosumer espresso machines, like ECM, Profitec, or Rocket Espresso.
This part regulates your boiler heating element via a diaphragm that expands or contracts as the boiler steam pressure raises or lowers. The switch behind the diaphragm activates the contacts and send power to the heating element telling it to turn on or off. It is by far the most common pressurestat used in our industry.
Most European espresso machine manufactures use British Standard Pipe (BSPP) fittings in their equipment. To measure a fitting, one measures the inside diameter of the male thread on a fitting. Most Sirai have the same fitting: ISO 228 G connection 1/4″M for pipe ø 4×6 mm. This presurstat can replace most full size pressurstats from Parker as well.
