Hoerbiger-Origa has enhanced its intelligent proportional pressure control valve, Airfit Tecno, with a redesign that improves its performance and ensures it's reliability in the most arduous application zones.

When the Airfit Tecno range was first introduced, its combination of piezoelectric technology and precision miniature component engineering completely redefined user expectations for speed and precision of air pressure control (Plate 4).

Plate 4 The Airfit Tecno is smaller than a computers' mouse

Smaller than a computer's mouse, Tecno can handle a flow rate of up to 380l/min, providing pilot, main pressure regulator valve and electronic controls in a single package. At its heart, instead of conventional solenoid technology, is a piezo chip which functions as a continuously operating 3/2 way pilot control valve. By applying a variable signal of less than 0.25 W to a cantilevered piezo element between inlet and outlet, the control airflow may be varied. The output pressure control signal is then amplified via a diaphragm mechanism to control the main pressure regulating valve.
