Tightening torques for screws to fix the valve pin in the valve pin retainer (pneumatic and hydraulic drive units)
•
The tightening torques given above are only valid for unlubricated screws. All parts must be clean.
•
If the screw has been tightened with the correct torque the valve pin in the valve pin retainer has a clearance of 0.02 mm
and can be rotated by hand. Jamming of the valve pin must be avoided!
