secure the doors onto the track.

of the doors to secure the doors onto the track.
In the center portion on the top of the doors there is a magnet used in conjunction with proximity sensors

2. Pneumatic Automatic Description/Operation

The Pneumatic Automatic Doors run on a single aluminum track mounted above the doors and a split track
mounted on the bottom of the doors. The doors are held on the track by four (4) stainless steel wheel
assemblies; two (2) are located on the top of the doors and two (2) are located on the bottom of the doors.
Additionally, in the center portion on the top of the doors there is a magnet used in conjunction with proximity

b. Operation
There are two (2) 1" bore x 20-3/8" stroke cable cylinders attached to the top of the doors to pneumatically
open and close the doors. When air is applied into the outside ports of these cable cylinders the doors will
open. If air is applied into the inside ports of these cable cylinders the doors will close. On each of the four
(4) ports is a flow control valve used for adjusting the opening and closing speeds of the doors. These flow
controls only vary the speed in the exhaust direction. Air to the cable cylinders is supplied through a 4-way
valve. When 24 VAC is applied to the valve, the doors open... if no power is applied, the doors close. A
3-way valve is used to supply air to the 4-way valve.
If the "EMERGENCY STOP" (E-Stop) is engaged, the air is automatically exhausted so that the doors can
be opened manually.
1) In a 2-Door application, there are two (2) additional cable cylinders a 4-way valve added for the operation
of the rear doors.
