Product description

Governed by the electrical valve control, the compressed air
connected to the device is directed alternately into both piston
chambers of the cylinder. The resulting dynamic effect extends
and retracts the piston rod connected to the piston.
You can adjust the pneumatic cushioning directly on the cylinder
using the throttle screws (8) inserted in both covers.
You can use the manual override (14) on the valve to switch the
valve if there is no electrical signal.
The optional proximity sensors allow the piston position to be
queried. The sensors are mounted on the tie rod (9).
With the optional CD12 series valve, you can configure a check-
choke valve that can be used to throttle exhaust air and thereby
adjust the piston speed.
