Note
· To maintain the mechanical gripping force, a 5/3-way valve with blocked middle position is to be used preferably.
· Please note that the service life of the gripper can be reduced considerably if you use it in extreme conditions (e.g. where coolant is used or dust
from casting or grinding processes are present). We cannot be held responsible in these cases. However, in most cases we can offer a solution;
please contact us.
