Instruction Manual

Operation 4-23
Valve Pressure Regulators
Depending on your application, valve pressure regulators (Figure 4-7) control the air
pressure for the blue and black air lines that connect to the fluid pump (see Table 4-7). The
Dispensing program toggles the pressure between the blue and the black air lines. The blue
air line will be pressurized while valve is ON and the black air line is pressurized when the
valve is OFF.
The Valve 1 Pressure regulator controls the pressure of the top blue and black air lines
located on the right side of the Dispenser head (see Figure 4-8, Figure 4-9, and Figure 4-10).
The blue fitting connects to the top of the fluid dispenser reservoir for a DV-6000 and DV-
7000 valve. For a DP-3000, both the blue and black air lines are used to actuate the 3-way
valve for toggling between the dispensing ready and refill or prime states.
For more details on how the air is used for fluid pump operation, see the appropriate manual
for your specific fluid pump.
Consult the fluid pump manual for the recommended setting for your fluid pump.
