6. Welding the pins (key 7):
When welding the pins to the ball ears,
use a compatible filler rod material. For
CG8M (317 stainless steel) V-notch
balls, use a 309 or 309L filler rod.
Tack weld both pins (key 7) to the ball ears with a
3/8-inch (10 mm) diameter weld. (Note: Good weld
penetration is required on both the pin and ball ear.)
7. Tighten the bottom flange nuts using the following
torque values: For 14-inch valves, 75 lbf ft (102 N m);
for 16-inch valves, 104 lbf ft (141 N m); and for
20-inch valves, 130 lbf ft (176 N m).
8. Lift the valve and place it with the outlet flange face
flat on the protected working surface. Use the lever
from the actuator, or provide some other safe method
to rotate the V-notch ball into the closed position. The
inlet flange face should be up to allow the installation
of the ball seal. The V-notch ball should be centered
within the valve opening.
9. Refer to the Ball Seal Replacement procedures to
install the ball seal and seal protector ring.

Actuator Mounting

Standard flow direction is with the seal protector ring
(key 3, figure 9) facing upstream. Install the valve with

Note
the drive shaft horizontal and the V-notch ball closing
in the downward direction (see figure 7).
WARNING
The V-notch ball (key 2, figure 9) closes
with a cutting motion. To avoid personal
injury, keep hands, tools, and other ob-
jects away from the V-notch ball while
stroking the valve.
Actuator travel must be adjusted before installing the
valve in the pipeline because it is not possible to accu-
rately determine the closed position once the valve is
in the line.
The actuator can be right or left-hand mounted in any
of four positions as shown in figure 7.
Right-hand mounting—Actuator is on
the right side of the valve when viewed
from the valve inlet.
Left-hand mounting—Actuator is on the
left side of the valve when viewed from
the valve inlet.
However, when changing the valve from right to left-
hand mounting, or visa versa, a different valve drive
shaft and V-notch ball (key 6, figure 9) are required. If
a new shaft and V-notch ball are required, refer to the
bearing and V-notch ball maintenance procedures and
the parts list in this manual.
