Pneumatic Valve Bank
Electro-pneumatic solenoid valves
provide control of pneumatic operations
through the use of machine function
feedback. The pneumatic valve bank
controls the movements of the machine
by converting electrical signals from the
PLC into airflow to the pneumatic
cylinders that control machine
movements.
Each machine movement is able to be
performed immediately once the
previous pneumatic function has been
completed.
All of the solenoid valves are located on
the pneumatic valve bank. The valve
bank is located on the operator’s side of
the machine on the main frame.
WARNING!
As the solenoid assembly de-energizes, either as part of
the machine control sequence or in the case of an
electrical failure, the possibility of unwanted actuator
movement must be considered, so use caution when
performing maintenance.
