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 valve. Fluid is filtered
through the manifold filter before entering the valve
fluid inlet port.
When air moves the piston and rod from its seat, it
opens the fluid outlet. When the air shuts off, the
spring pushes the piston and rod 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
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.
• Dispense 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.
