Proportional 5/3-way directional valve

The proportional valve transforms an analog electrical input signal into corresponding opening cross-sections at the outputs. At half nominal voltage i.e. 5 V, the pneumatic mid-position is taken. Here all leading edges are closed, so that no air flows through the valve. Beneficial static and dynamic characteristics with minimal hysteresis (less than 0,3 %), short actuating time (typically 5 ms), and a higher upper frequency limit (approx. 100 Hz), are achieved through an integrated electronic position control for the slide distance. Thus the valve, as control element and especially in combination with a higher ranked position controller, is suitable for the positioning of a pneumatic cylinder.
