On most of the GEA Tuchenhagen valve types, solenoid valve Y1 internally
guides the main control air through the switch bar into the main actuator. The
external air connection Y1 is provided in addition.
Hint!
To ensure adequate compressed air supply to the process actuators, a
max. of 2 solenoid valves are electrically activated at the same time!
It must be ensured that there can be no simultaneous control of the
actuator or the lifts at the same process valve!
