1.5.1 Accident prevention
WARNING
Operating medium leaving/leaking out of the way valve may get in contac
t
with hot machine parts, posing a risk of fire.
The way valve is under pressure!
On operation with manual operation knob, uncontrolled piston rod movements
may result posing a risk to persons and property. This movement may pose a
risk to both individuals and objects.
During operation of the way valve, the output pressure may vary severely in
case of a failure of the electric energy or of malfunctions of the control
electronics integrated in the way valve. The piston rod of a hydraulic cylinder,
for example, may move uncontrolled posing a risk to persons or objects.
WARNING
The way valve is a hydraulic unit. In case of improper use, operating medium
being under pressure may leak out. The operating medium poses a risk to the
health and life of the operating staff. Prior to performing any work on the way
valve, switch off the hydraulic supply system.
In case of improper use, operating medium being under pressure may leak
out on the sealing surfaces.
On commissioning or operation of the way valve, spraying hydraulic oil ma
y
get into the eyes causing blindness. Wear safety goggles for all work
performed on the way valve.
During operation, the outer surfaces of the way valve and the hydraulic
connecting lines may become hot due to the operating medium. Any contac
t
may cause injuries by burning. Prior to performing any work on the way valve,
let the way valve cool down.
CAUTION
Prior to performing any work, switch off the hydraulic supply system.
On commissioning or operation of the way valve, the end of the piston rod
directly or indirectly driven by the way valve may move uncontrolled in case o
f
a failure of the hydraulic or electric energy, due to malfunctions in the maste
r
control or on the way valve. This movement may pose a risk to both
individuals and objects. Prior to performing any work on the way valve, switch
off the hydraulic and electric auxiliary energy.

User Information
NOTICE
Electrical components are integrated in the way valve. These components
may be destroyed, e.g. when performing electric welding work near the way
valve. Prior to performing any electric welding work near the way valve,
remove all electric connecting lines.
1.5.2 Environment
NOTICE
On assembly, disassembly or improper use of the way valve, operating
medium may leak out. Operating medium getting into the sewage system o
r
open soil causes severe environmental damages. Collect any leaking
operating medium and dispose of it in accordance with the national statutory
provisions.
1.6 General description of the way valve
In hydraulics, a "Voith way valve" serves to release, block or change the flow direction
of the hydraulic fluid by converting a setpoint signal, 4mA to 20mA, into a linear
movement of the control piston.
The way valves differ according to the following main features:
1. Number of positions
2. Number of flow routes
3. Number, size and kind of connections, e.g. nominal diameter, thread, ...
'Voith way valves' are suitable for fixing to hydraulic cylinders or to adapter plates and
4-way blocks.
1.7 Proper use
The way valve serves to transform an electric set signal, e.g. 4 - 20 mA into a flow rate
variable in direction and size. This allows, for example, remote-controlled, infinitely
variable adjustment of a hydraulic positioning cylinder with spring resetting for the
positioning of control valves on turbo machinery.
The maximum pressure indicated in the installation and operating manual must not be
exceeded.
Proper use also includes observing this installation and operating manual and
complying with the inspection and maintenance instructions.
