4.2.2.12. Discharge Cone
The discharging cones on horizontal silo
vehicles (SSL) are placed as facing
downward. Unlike SSK vehicles, these co-
nes do not have a cover, emptying opera-
tion is done by means of fluidiser air, jet air
and compression valves from the dischar-
ging hole which is installed optionally.
In picture, the jet air (1) is seen on the left,
the fluidiser air (2) is seen on the right side.

4.2.2.13. Butterfly Valve
It is used when the material is emptied on
the ground with gravity. This valve is nor-
mally blinded, it is provided optionally.
Open the valve by turning the lever (1)
which is seen in the picture and empty the
material on the ground.
When gravity discharge is made
(with gravity, without giving air
into the tank), one of the man-
hole cover must be opened before star-
ting the discharge.
Check whether there is pressure inside
the tank.

4.2.2.14. Pinch Valve
It is located at the outlet of the discharging
cone, just before the jet air coupling. The
pinch valve (1), which is closed while the
material is transporting, is opened when the
material is emptied.
Opening the valve:
The pinch valves are opened and closed
pneumatically. The control levers of the
pinch valves are located either in the rear
tool box with lock mechanism or at the side
of
the vehicle according to the vehicle’s
construction. To open the valves pull the
button towards yourself, when the button is
pushed, the valve is closed, when the but-
ton is pulled, the valve is open.
