Glendale Heights, Ill.— Hoerbiger-Origa Corp.’s new line of pneumatic directional control valves, Piezo 2000, combine the benefits of Piezoelectric technology with poppet and packed-spool valve constructions. The “Pill” is the heart of the valve which contains the orifices. Encased between the two shell halves is a reed similiar to a bimetallic strip constructed of two different length ceramic strips. An electrical connection is attached to the ceramic reed. When voltage is applied, it changes the length of the ceramic strips causing it to bend in the direction of the shortest strip. The result is the opening of the valve’s pressure orifice. This signal, also called pilot pressure, causes the main valve spool to shift resulting in a position change of a valve actuator or cylinder. The valve offers a variety of benefits, which include: long life, the operating signal can be digital or analog, no heat build up generated, universal voltages from one valve operator, simplified inventory and lower costs, and installation and maintenance costs reduced.
