The pilot air must be applied immediately after it is switched
on at the minimum pressure specified in Appendix A, Tab. A/6
for the relevant valves. Otherwise it is not ensured that the
valve will switch directly (see diagram).
If the pressure is less than the minimum specified, 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).
