1 Application and function
The VPPM is intended for controlling a pressure
proportional to a specified setpoint value (input
word). A built-in pressure sensor records the
pressure at the working port and compares this
value with the setpoint value. If there are devi­
ations between the actual value and the set­
point value, the control valve is actuated until
the outlet pressure reaches the setpoint value.

4 Installation
4.1 Mechanical
Make sure there is sufficient space for the connecting cable and tubing connec­
tions. In this way you will prevent the cable and tubes from being bent.
Place the VPPM as close to the consumer as possible. This leads to improved
control precision and shorter response times.
Wall mounting
Fasten the in-line valve of size
x
" and
¼
"
at the intended position with two M4 screws.
If necessary, use bracket type VAME-P1-A
(
è
Fig. 5) to do this. When using the bracket,
the VPPM may only be loaded statically.
Fasten the in-line valve of size
½
" at the
intended position with two M5 screws
(tightening torque 2.0 Nm).
Mount the flange valve of size
x
" and
¼
"
onto the manifold rail VEABM-P1-SF-G18…
(tightening torque approx. 1.5 Nm). Fasten
the manifold rail at the intended position
with two M6 screws.
