WELDING INSTRUCTIONS
CAUTION:
failure to follow these instructions
could result in serious damage to the valve seats
and seals.
1. To prevent weld splatter damaging the ball
surface and to facilitate the later removal of
the center section, ensure the valve is in the
open position.
2. Locate the valve in the pipeline and
tackweld the valve in position.
3. Loosen and remove the body bolts
(010) and nuts (011), allowing the body
(001) to be removed from between end
connectors (009).
When removing the body (001), ensure
the body seals (012), seats (101) and seat
retaining ring (103), remain in the original
locations.
4. Complete welding process, taking care
to protect the sealing faces of the end
connectors (009) from weld splatter. Allow
cooling of the ends before reassembly.
5. Reassembly:
a) Check the body seal (012), seats (101),
ball (100) and seat retaining ring (103)
making sure they are clean, undamaged
and in original locations and that the ball
is in the open position.

b) Check sealing faces of end connectors
(009) to ensure the surface is clean and
not damaged by weld splatter.
c) Relocate the body (001) between end
connectors (009), taking care that the
pipe ends are sufficiently apart to provide
clearance to slide the center section into
position between the ends. Replace body
bolts (010) and nuts (011) and retighten to
recommended torques.
6. Inspect for leakage at plant start-up and
adjust if necessary.
CAUTION:
if seats or seals are in any way
damaged, do not reassemble valve without
replacing damaged components.
OPERATION
All Emerson ball valves are quarter turn.
Handle operated valves provide visual indication
of the valve position. When the handle is across
the line of the valve, the valve is closed, and
when the handle is in line with the valve, the
valve is open.
Actuated valves are available and Emerson
has various options of pneumatic and electric
actuators.
For further details on fitting actuator, refer to
the mounting instruction sheet.
