AIR CONNECTIONS
NOTE
For quick response, Nexen recommends a quick exhaust
valve and short air lines between the Control Valves and
the product. Align the air inlet ports to a down position
to allow condensation to drain out of the air chambers
of the product.
CAUTION
Low air pressure will cause slippage and
overheating. Excessive air pressure will
cause abrupt starts and stops, reducing
product life.
All Nexen pneumatically actuated devices require clean
and dry air, which meet or exceeds ISO 8573.1:2001
Class 4.4.3 quality.
The following is a common air supply scheme used with
this product. This is an example and not an all-inclusive
list. All air circuits to be used with this product must be
designed following EN983 guidelines.
