Overview Overview
The valve uses the air-opened, spring closed mode
of operation. It uses a three-way exhausting solenoid
to control the piston inside the dispense module.
Fluid is filtered through the manifold filter (C) before
entering the dispense module fluid inlet port. Then
the fluid is filtered one final time through the module
filter (P), which is located in each module, directly
before the ball and seat.
When air moves the piston rod and ball from its seat,
it opens the fluid outlet. When the air shuts off, the
spring pushes the piston rod and ball into its seat and
closes the fluid outlet.
The gun 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

Grounding Grounding
The equipment must be grounded to reduce the
risk of static sparking. Static sparking can cause
fumes to ignite or explode. Grounding provides an
escape wire for the electric current.
Pump: follow manufacturer's recommendations.

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.
