The pilot air supply must reach a pressure of 3 ... otherwise,
there is no guarantee Otherwise it is not ensured that the
valve will switch directly (see diagram).
If the pressure is less than 3 bar, there may be a delay before
the valve is switched, in spite of an electric signal being
present. The gradual pressure build-up of the overall supply
does not affect the actuator in that case. The actuator would
react suddenly (e.g. a cylinder would extend or retract
suddenly, depending on the valve function).
