Manifold and Circuit Board
Description
See Figure 19. The Prodigy High-Density powder, Low-Volume air (HDLV) powder feed pump transports
precise amounts of powder from a feed source to a powder spray gun. The pump control manifold controls
the air flow in and out of the pump.
Manifold Components
Item
Description
Function
1
Solenoid Valves
Control the air flow to the pump during operation.
NOTE:
Refer to
Solenoid and Control Valve Functions
on
page 35 to identify each valve’s specific function.
2
Pattern Air Flow Control
Valve
Regulates the air pressure to the spray gun’s nozzle, which
shapes the powder spray pattern.
3
Pump Air Flow Control Valve
Regulates the positive air pressure to the fluidizing tubes,
which dispenses the powder out of the tubes.
4
Vacuum Air Solenoid
Turns the airflow through the vacuum generator on or off.
5
Vacuum Generator
Works on the venturi principle to generate the negative air
pressure required to draw powder into the fluidizing tubes.
—
Solenoid Wiring Harness
Connects the manifold solenoids to the circuit board.
—
Circuit Board (Not Shown)
Contains the hardware and software that controls the timing
of the solenoid and flow control valves.
NOTE:
The circuit board provides control for up to two
pump control manifolds.
