Our History

Founded by Guido Spriano, a pioneer of industrial instrumentation, Spriano® begins its activity manufacturing pressure and temperature gauges.
Spriano® is the first Italian company to manufacture a modulating pneumatic controller, contributing a consistent technical improvement to Industrial Automation and Control in the
Rubber, Oil & Gas and food industries.
Spriano® engineers and starts manufacturing a complete line of Control Valves branded MEC-RELA®, providing effective and efficient solutions for Industrial applications.
During the 80’s, Spriano® completes its technological transfer from pneumatics to electronics by developing a complete line of innovative instruments, the 2-wire system and microprocessor-based electronics with both transmission and control function, thus providing a complete process monitoring system to the end user.
Spriano® makes the history of industrial instrumentation, being permanently hosted in the ‘Sala GISI’ inside the National Museum of Science & Technology ‘Leonardo da Vinci’ in Milan.
Spriano® develops its presence worldwide.
Spriano® moves the production site in the Southern Milan area, with the new brand Spriano® Technologies.
