2009 Nordson Corporation
Description
See Figure 1. The Nordson AG-900+/AG900+S modular dispensing applicator is a
noncirculating unit that applies solid and foamed high performance materials such as
silicones, plastisols, urethanes, epoxies, butyls and hot melts. The applicator is compatible
with a variety of Nordson systems and is well suited for automated dispensing equipment.

The applicator is pneumatically triggered by a customer supplied external solenoid. The
applicator assembly includes a module, and either a pressure regulator (heated or
unheated) or applicator adapter body.
The AG-900+/AG900+S dispensing applicator is available as a zero cavity needle/nozzle
design, or can be provided to accept standard extrusion nozzles.

Part 1098464A
Heated AG-900+/AG900+S applicators have replaceable heater cartridge(s) in the heater
block assembly mounted to the module. Resistance temperature detectors (RTDs) in the
hose and in the heater block monitor temperature. Cordsets from the hose and from the
heater block are connected electrically to a controlled power source such as a FoamMix
processor or a standalone temperature controller.
AG900+/AG900+S applicators are set up from the factory to operate as
air-open-spring-close actuation for use in dispensing lower viscosity materials. Air-close
operation can be used when using materials of higher viscosity.
NOTE: If the air−close will be used, order part number 1096469 solenoid assembly
with tubing.
Needle and Nozzle Design
AG-900+/AG900+S applicators accommodate needle and nozzle designs selected for each
application requirement. The zero cavity needle/nozzle applicator describes zero space
downstream to the cut-off where the nozzle and needle join. This prevents material from
leaking, clogging and backing up in the applicator-on positions.
Material Pressure Regulator
AG-900+/AG900+S applicators are available with an optional material pressure regulator
attached directly to the applicator module. This regulator provides consistent material
pressure to maintain constant output rates.
Hose Connections
The following heated and unheated hose connections are available:
dual-axis (X and Y) swivel
fixed, 90
