In 1969 SIRAI® started to market its own pressure switch. A few months later, it launched the version for water temperature control in espresso coffee machines.
The appreciation of the market has been demonstrated by the high sales: over 6 million pressure switches suppliers sold in 40 years
There have been major developments and improvements in the espresso coffee machines over this period but the pressure switch was never a problem, as it revealed itself suitable for tomorrow’s standards from the very beginning.
SIRAI®’s contribution has been to guarantee over time a high precision, reliable product in terms of mechanism and materials while, at the same time, developing cocks, on the basis of the experience acquired, that extended the precision of action to cover the whole machine. The result was the manufacturers of solenoid valves for the “coffee sector” for both the inlet and delivery of the water (L120 - L334) and those for special applications, for which the “pinch” (S105) or the “DRY” (D318) models have been used.
SIRAI® has also accepted the challenge of creating a new generation of pressure professional switches, convinced that a product that is unequalled can be improved only by experience gathered over 40 years.
Thus, we are proud to present the new P303, a pressure switch that combines the quality and performance of its predecessors with a smaller size and very easy wiring. In compliance with RoHS Directive, this model will be sold side-by-side with the current P302, which will continue to be available in the catalogue, further evidence of the company’s commitment in guaranteeing a vast and ongoing choice
