2-40. WATER MANIFOLD ASSEMBLY (CONT)
Ball valve crank (49) and anchor bracket (15)
must be exactly in line. The air actuator must
not be slanted or cocked with relation to the
plane of crank move-merit. Binding between
the crank and anchor bracket will occur if
they are misaligned.
1. Check clearance after piping the machine.
Maintain 1/16 ± 1/32 clearance between the open
and closed crank stop (48) positions to prevent valve
stem damage when closed and ball overtravel when
Overtravel will cause the valve to throttle the
flow of incoming water. This has a
detrimental effect on valve life and also
increases filling time.
2. To adjust both the alignment and clearance,
loosen the anchor bracket (15) and perform the
following as needed:
a. Rotate the anchor bracket (15) around the pipe
(6) to adjust alignment.
b. Slide the anchor bracket (15) up or down the
pipe (6) to adjust clearance.
3. Adjust the needle valve (50) (if equipped) to
slow the opening and closing of the air actuated ball
valve assembly. One quarter to one half turn is
4. Ensure that all air actuated ball valve
assemblies close at the same speed.
