Fig. 2 An air cylinder was used to
open and close the original mechanical
valve as shown. This air cylinder was
controlled by a manually operated 2-
way air valve. The air cylinder moves
the mechanical valve from its closed to
open position. The amount of opening
was pre-set by the operator by adjust-
ing a nut on the linkage of the air cylin-
der to limit the stroke.
Fig. 3 This figure shows an ammeter
reading of approximately 8 amps, the
no-load or no shot flow condition. A
conventional panel ammeter (0-30
Amps) was used to indicate motor
amps and relative shot flow rate. It is
not uncommon for these meters to be
inaccurate because metallic dust col-
lects inside the meter movement
mechanism. This prevents the meter
from displaying the proper amperage.
