PNEUMATIC CONNECTIONS
NOTE: Nexen's EN50 requires clean, pressure
regulated air for maximum performance and long
life. Your Nexen Distributor carries filters and
regulators specifically designed to operate with
Nexen products.
A Pre-filter (rated at 5.0 micron or less) removes
large particles from the air supply. The Final Filter
(rated at 0.1 micron or less) is used to filter the air
before it enters the Nexen EN50.
Clean all pipelines to remove dirt and scale before
installation. If you use a pipe compound when
installing the pipe or tube fittings into the Nexen
EN50, use a Teflon dope as a sealant.
1. Apply a minimum amount of pipe sealant
compound to the male threads of the fitting only;
then, start at the third thread back and work away
from the end of the fitting to avoid the possibility of
contaminating the Nexen EN50.
NOTE: The inlet and outlet ports are labeled on the
side of the EN50. User connections should be made
to the inlet and outlet ports located in the bottom of
the valve body only (See Figure 2).
2. Install the Nexen EN50 in the air line and securely
tighten the connections.
3. Install the plugs supplied with the Nexen EN50 in
all unused ports.
