Compressed air supply ( 1 )
S Use only dried, non-lubricated, 5 μm filtered compressed
air from 5 to 7 bar.
You will require a service unit with a 5 μm filter for protecting
the proportional directional control valve against damage.
Service unit ( 2 )
S Use a service unit consisting of a compressed air filter
and a regulating valve (e.g. type LFR-...-D-... with 5 μm
filter element) as well as a safety start-up valve
(e.g. HEL-...-...):
– without lubricator
– with a 5 μm filter
– with sufficiently large standard flow corresponding to
the air requirement of the connected drive during
positioning. Reference value: twice the rated flow of
the valve (type MPYE-5-...), e.g.:
