Spray Bar
The spray bar used on the Model
BC-502/ CRC distributor is a full
circulation type spray bar. The
spray bar permits circulation of
asphalt throughout the entire
interior of the bar structure. This
configuration allows the fully
enclosed spray valve bodies to be
totally immersed in asphalt,
assuring immediate
application of material when the valve is opened (instant open/close).
The “Tri-Valve Manifolds” that release the spray are open and closed by
electrically controlled air cylinders that directly couple to each poppet
within the Tri-Valve Manifolds. The spray valves are actuated when the
operator actuates the corresponding switches on the Cab Console. An
optional mechanical linkage system is also available in lieu of the Tri-
Valve Manifolds.
Folding Wing Configurations
The spray bar can be provided with
single fold, double-fold, or triple-fold
wings, permitting maximum coverage
as wide as 24 feet. A double fold wing
configuration is pictured here. The
outermost segment of a multi fold
wing is the first to respond when the
switches that control wing movement
are actuated. Spray valves are spaced
along the bar on 4 inch (102-mm) centers. Valves are controlled in
groups of three per switch, occupying 12 inches or 305 mm.
