Festo – CLR – 2017-05e English 11
Pneumatic installation
Please note
The clamping finger from Festo matches optimally the CLR-... and does not
require any air restriction.
S Note that if user-made clamping fingers are used, the mass moment of inertia
must be calculated.
A higher mass moment of inertia than that specified for the clamping finger
set from Festo requires a reduction in the stroke time of the CLR-... by the use
of one-way flow control valves.
The dimensions of the cone and the diagrams for determining the stroke time
as a factor of the mass moment of inertia can be found in the Festo cata
logue.
S Remove the adhesive labels on the compressed air connections.
S Check to see if accessories are required as shown in the following table.
Type
Designation Function
HGL-... Non-return valves with
closed-loop control
If there is a pressure falure, the pressure in
the piston chamber will be retained.
GRLA-... /
GRLZ-...
One-way flow control val
ves
The piston speed can be modified.
VZS-... Compressed air reservoir Fluctuations in pressure will be reduced in
the downstream-switched compressed air
string.

S Use short tubing lines for your
application.
Short lines optimize the pressurisation
time.
S Screw the one-way flow control valves of
type GRLZ-... or GRLA-... into the com
pressed air connections.
S Connect the tubing of the CLR-... to the
compressed air connections.
