Technical data
Medium
Compressed air, filtered, lubricated
or non-lubricated

oil with DVI values < 8 (DIN 53521)
and ISO viscosity class 32-46
(DIN 51519), Filtration 25 - 50 mm
Operating Pressure:
29 to 145 psig (2 to 10 bar)
Temperature range:
14°F to 140°F (-10 to 60°C)
To secure the safety function of the
valve at subzero temperatures it is
important that the air is dry enough
to prevent an icing of valve and
silencer.
Mounting position:
Preferably vertically
Additional equipment:
Soft clutch module
Soft brake module
Safety silencer
Failure indication elements
Nozzle for overlap adjustment
(exclusively XSz32 and 50)
