2.2 Proper use
The way valve serves to transform an electric position 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 for positioning of control valves on
turbo machinery.
2.3 Important information
The following information refers to the entire instruction manual and is to be observed in
addition to the individual instructions.
Accident prevention
It is imperative to observe the requirements of the relevant standards and regulations
when connecting a way valve in explosion-proof design.
There must not be any potentially explosive atmosphere during all works performed,
such as e.g. transportation, storage, installation, electrical connection, commissioning,
test run, maintenance and servicing!
Operating medium leaving/leaking from the way valve may get in contact with hot
machine parts, posing a risk of fire.
