4. Connect the black nylon tubing between the AIR port
of the valve and the AIR port of the nozzle. Repeat for
the remaining nozzles.
5. Connect compressed air to the inlet of the regulator on
the top of the valve stack.
6. Connect pressurized fluid to the liquid inlet on the
bottom of the valve stack.
The nozzles in the 4210 standard family can be connected
to a controller, such as the SPR-2000
™
controller, so that
each nozzle has its own fluid and air supply (is directly
connected) or so that they share a fluid line (daisy
chained). The direct method (Figure 19) is preferred
because it gives consistent fluid and air pressure across all
nozzles in the bank. The daisy chain approach (Figure 20),
has fewer connections back at the solenoid valve bank,
but is more susceptible to variations due to differing fluid
pressures at each nozzle. The same options are available
with a manual air valve, although it is rare a manual valve
is used with more than one nozzle.
Fluid & Air Connections
4210 Series (Direct Operation)
1. Connect clear nylon tubing to the LIQUID port of the
nozzle. Route the tubing to the valve stack. Ensure that
there is no fluid pressure on the valve stack, and plug a
straight male quick disconnect fitting into the appropriate
female quick disconnect of the valve stack.
2. Remove the nut from the male quick disconnect and trim
the tube length such that it will just slide over the barb
on the fitting.
3. Slide the nut onto the hose and then push the tube onto
the barb of the quick disconnect. Use a 1/2” wrench to
keep the male quick disconnect from rotating and tighten
down the nut with a 3/8” wrench. Repeat for the remaining
valve/nozzle combinations.
