A 1/8 NPT female Air Inlet Fitting (Item 18) is provided in the
Piston (Item 13) for the air line connection. The Air Hose
Assembly (Item 19) must be used so that no side forces
are introduced to the air chamber-piston assembly.
Bearing drag on the hose during operation may be relieved
by securing the hose to a support.
The use of rigid pipe or tubing when
connected directly to the BW Clutch
will prevent proper actuation of the BW
Clutch.
All Nexen pneumatically actuated devices require clean and
dry air, which meets 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.
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.
Low air pressure will cause slippage and
overheating. Excessive air pressure will
cause abrupt starts and stops, reducing
product life.
