Functional principle
When the pilot valve is activated, the angle valve is closed by
the pressure spring. The position indicator is invisible.
When the pilot valve is deactivated, the angle valve is opened
by the pneumatic actuator. The green position indicator be-
comes visible.
The final positions can be polled by the electrical position
indicator.
