Functional Principle
When the pilot valve is activated, the pneumatic actuator
opens the angle valve. The visual position indicator becomes
visible, and the electrical position indicator "valve open" is
activated.
When the pilot valve is de-energized, the pneumatic actuator
is vented, and 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 activated.
