AIR CONNECTIONS
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. All Nexen pneumatically actuated devices require clean,
dry air that meets or exceeds ISO 8573.1:2001 Class
4.4.3 to quality.
CAUTION
Low air pressure will cause slippage and
overheating. Excessive air pressure will
cause abrupt starts and stops, reducing
product life.
NOTE
For quick response, Nexen recommends a quick
exhaust valve and short air lines between the
Control Valves and the unit. Align the air inlet
ports to a down position to allow condensation
to drain out of the air chambers of the product.
REFER TO FIGURE 4.
