1 Functional Principle
1.1 Valve with Pilot Valve, Normally Closed
Opening action
When the pilot valve is activated, the angle valve is opened by
the pneumatic actuator. The visual position indicator becomes
visible and the electrical position indicator "valve open" is acti-
vated.

Closing action
When the pilot valve is deactivated, the angle valve is closed by
the pressure spring. The visual position indicator is no longer
visible and the electrical position indicator "valve closed" is acti-
vated.
