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 moves the
piston rod connected to the piston back and forth.
You can adjust the pneumatic cushioning directly on the cylinder at
the throttle screws inserted on both covers.
You can use the yellow manual override on the valve to switch the
valve if there is no electrical signal.
Depending on your configuration, there are two throttle screws on
the pneumatic valve that can be used to throttle the exhaust,
thereby adjusting the piston speed.
The optional proximity sensors allow the piston position to be
queried at different positions.
