The valve is designed for extreme conditions, where high

switching frequencies and a long service life are required, but
dead space cannot be permitted inside the valve.
Control functions can be realised using a switching frequency
control system.

The medium comes into contact not only with the ceramic discs,
but also with housing parts and seals. Alongside the standard

on operating conditions.

This slide valve type is designed for very small volume flow
rates in the nominal width range from below 1 mm up to 10 mm.

Principle of operation
At the actuator area, the actuating pressure gene-
rates a force balanced by the springs. The nominal
stroke is determined by the number of springs and
their preload. The stroke is proportional to the
actuating pressure.
Its effective direction depends on the mounting
position of the springs, and the actuating pressure
connection.
A coupling connects the drive rod with the stroke
