Fault description Cause Remedy
Valve does not respond. Operating voltage not applied. Check the operating voltage
connection.
No setpoint voltage. Check the controller and con-
nection.
Working temperature is too
high. Valve is in temperature
shut-off. Switch off the valve, let it cool
down and restart.
Reduce ambient temperature
and / or temperature of
medium.
Valve normally open:
The working pressure at (2)
falls to the level at (3) (ambient
pressure or vacuum). Cable break setpoint input Check connection to setpoint
generator.
Replace electrical connecting
cable.
Valve normally closed:
The working pressure at (2)
deviates upwards or down-
wards from the setpoint value
(working pressure is neither
pressurised nor exhausted). Cable break setpoint input Check connection to setpoint
generator.
Replace electrical connecting
cable.
Setpoint value not reached. Input pressure at (1) is too low. Increase input pressure at (1).
Maintain permissible maximum
operating pressure

1) The valve can be operated at an input pressure within the specified range. It must be noted here that the
specified control quality is only fulfilled with a permanent supply within the operating pressure range and
that the control pressure can reach the maximum available input pressure.
2) The specified control quality is only achieved if there is a permanent operating pressure supply at the
valve within the specified range.
3) Active regulation is only from a setpoint value of 1% FS, below which the valve is at zero point suppres-
sion.
4) For variants VPPI-...-1V0H-... 0 % of the setpoint value corresponds to 0 bar and 100 % of the setpoint
value corresponds to –1 bar.
