The position of the control piston marked in Fig. 1 is designated as hydraulic center in
which the throughflow cross sections are virtually zero and the cylinder has taken a
constant position s. To avoid a generation of the magnetic force, that is required for the
hydraulic center, by a system deviation, a magnetic force offset is set with parameter PM
so that the system deviation becomes zero and the setpoint w becomes equal to the actual
value s or x.
Function of manual operation knob
Instead of the magnetic force F
Mag
a force can be set that is transmitted to the control
piston via the tappet. This way, the control piston can be moved without electrical
connection and the cylinder can be moved to an end position. It is not possible to approach
any positions s of the cylinder with the manual operation knob.

Packing, Storage and Transportation
Packing
The way valve is supplied in special packaging.
Storage and preservation
A galvanic corrosion protection will be applied to the outer surfaces of the way valve. On
delivery, the inner parts of the way valve which are not surface-coated are moistened with
preservation oil.
Within Europe, this preservation is sufficient as corrosion protection for about 8
months, provided the way valve is stored in a dry location.
If it is intended to store the way valve for a longer period of time, special precautions have
to be taken. Coordinate such precautions for each individual case with Voith Turbo GmbH
& Co. KG, Crailsheim.
The ambient conditions for storage must be within the limits indicated in Chapter 1.
Transportation
It is not allowed to transport the way valve in an explosive atmosphere! This also
applies to the transportation of spare parts!
Improper transportation or lifting of the way valve may cause damage to property and
personal injuries.
Observe, in particular, that constraining forces do not act on the cable entry of the
control magnet (VRM) and that the connecting line is not damaged.
For transportation purposes, it is not allowed to keep the way valve connected to the
connecting line.
