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 or
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.
