Overview
The applicator uses the air-opened, air closed mode
of operation. It uses a ve-way exhausting solenoid
to control the piston inside the valve. Fluid is ltered
through the manifold lter (C) before entering the
valve uid inlet port. Then the uid is ltered one nal
time through the module lter, which is located in
each module, directly before the ball and seat.
When air moves the piston and rod from its seat,
it opens the uid outlet. To turn off the uid, the
solenoid redirects air to the top of the piston. The
air and spring work together to push the piston and
rod into the seat.
The applicator should be rigidly mounted and
remotely operated by a melter system and triggering
device. The melter system provides pressurized uid
to the valve. The triggering device controls the uid
ow by opening and closing the solenoid valve.

Grounding
The equipment must be grounded to reduce the
risk of static sparking and electric shock. Electric
or static sparking can cause fumes to ignite or
explode. Improper grounding can cause electric
shock. Grounding provides an escape wire for the
electric current.
