The positioning cylinders operate a valve that controls the mass flow needed to drive machinery. Voith I/H
converters ensure very precise and highly dynamic control of the mass flow. I/H converters change a constant
input pressure into a variable output pressure. A standard 0/4 – 20 mA signal specifies the output pressure.
The major components of the I/H converter are a hydraulic unit and a force-controlled electromagnet.
The I/H converter features a simple and compact design. This ensures reliable operation. The Mean Time
Between Failures (MTBF) for Voith I/H converters is over 600 years. Your equipment runs for a very long
period of time without unplanned downtime; availability is increased.
