4 Product overview
4.1 Function
The proportional-pressure regulator controls the pressure proportionally to a
specified setpoint value. A built-in pressure sensor records the pressure at the
working port and compares this value with the setpoint value. If there are devia-
tions between the setpoint value and actual values, the proportional-pressure
regulator is actuated until the output pressure has reached the setpoint.

5 Transport
Store and transport the product in its original packaging. Observe the weight, the
dimensions and the ambient conditions.
6 Assembly
6.1 Mounting clearances
During assembly make sure that there is sufficient space for the cable connection
and the tubing connections. Place the device as close to the consumer as pos-
sible. This leads to better control accuracy and shorter response times.
