(station width 11 mm)
7.1.1. Configuration and function
The pneumatic valves of Type 6524 and 6525 consist of an Ex-i pilot solenoid valve (Type 6104 or Type 6144)
and a pneumatic seat valve as an amplifier.
This operating principle enables high pressures to be controlled with low power consumption and short switching
times. Normally, the valves are equipped with an emergency manual override (versions without this feature are
available).
