G Nozzle Assembly
H Pour Nozzle
Within each nozzle assembly, there is an injection noz-
zle and needle valve kit (101) where the chemicals are
introduced into the mixing chamber. In the mixing cham-
ber, the two chemicals are impinged against each other
causing the mixing of the two components.
After dispensing is finished, the valving rod is hydrauli-
cally driven forward to the “closed” position to com-
pletely remove mixed material from the mixing chamber.
There is no need for additional cleaning.
With the valving rod closed, the fluid circulates from the
supply lines directly to the return lines. This creates con-
tinuous circulation of conditioned material through the
MixHead and back to the tank.
