2 Application and function
The VPPM−...C1 has been designed for regulating a pressure proportional 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 further until the
output pressure reaches the setpoint value.
