The direct-acting proportional valve Type 2822
can be used as a control valve for process
control and is suitable for technical vacuum. A
special design minimizes frictional and stick-slip
effects and provides an excellent span, repeatability
and sensitivity.
The valve is driven either by DC or by a highfrequency
PWM signal. With the input signal at
zero, it closes tightly owing to an elastomer seat
seal. Because of its almost silent operation, the
valve is specially suitable for medical applications.
