Fig.14: Control top (standard variant in IP66)
E1 Exhaust air of the main stroke Y1 (sound absorber or exhaust air
throttle, optional)
Connection E1 must not be closed!
E2 Safety vent against excess pressure and exhaust air of lifting
actuators Y2 and Y3
Non-return valve
Connection E2 must not be closed!
P Central air supply with integrated filter
Optional: supply air throttle
N Air connection for spring force backup
Only with logic element NOT
Y1 Air connection for external main stroke connection
with plug (23)
Y2 Air connection for lifting the valve disk
Y3 Air connection for lifting the double-disk or for the main stroke of an
external process valve
23 Plug
Control air pressure can be present at the plugs for the air
connections!
Before removing a sealing plug (23), make sure that the respective
air connection is pressure-free!
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!
