Overview
The applicator uses the air-opened, air-closed mode of
operation. It uses a five-way exhausting solenoid to
control the piston inside the valve. Fluid is filtered
through the manifold filter (C) before entering the valve
fluid inlet port. Then the fluid is filtered one final time
through the module filter, 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 fluid outlet. To turn off the fluid, 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 fluid to the valve.
The triggering device controls the fluid flow 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.
Pump: follow manufacturer's recommendations.
Applicator: grounded through electrical connection.
Air compressor: follow manufacturer's
recommendations.
Fluid supply container: follow local code.
Solvent pails used when flushing: follow local code.
Use only conductive metal pails, placed on a grounded
surface. Do not place the pail on a nonconductive
surface, such as paper or cardboard, which interrupts
grounding continuity.
To maintain grounding continuity when flushing or
relieving pressure: ensure mounting manifold and
electrical power connector are grounded properly.
