2 Application and function
The VPPM-...C1 is intended for regulating pressure proportionally to a specified
setpoint value. A built-in pressure sensor records the pressure at the working line
and compares this value with the setpoint value. If the actual value differs from the
setpoint value, the regulating valve is actuated until the outlet pressure reaches
the setpoint value.
