 Installation of Threaded Valves
Valve can be screwed on without the use of union or with the end
caps removed from the body
The use of a thread sealant is recommended
Apply wrench only on the hexoctagon valve end being
tightened Do not tighten by applying torque to the opposite end
cap or other valve component
CAUTION
Tightening by using the valve body handle or the opposite end
cap can seriously damage the valve use a wrench on both the
near end cap and pipe to avoid applying torque to the body
through the bolting
In some applications screwed valves may be back-welded
Disassemble as per instructions for weld end valves
Confirm that the end cap bolt holes are aligned with the body
bolt holes on both ends and that the end caps are parallel and
correctly spaced to fit the valve body before reassembly or back
welding
Make up both of the threaded connections normally and then
remove the body assembly as described in Section  for weld-
end connections before back welding the threaded connection
NOTICE
Do not use the body bolts to pull the pipe ends together or
into alignment
 Installation of Extended Weld-End Valve
NOTICE
Ensure that appropriate weld procedures are implemented that
are compatible with the materials used
Valves with  inch or longer extended weld ends do not require
disassembly for installation welding Valves with non-extended
ends should follow the requirements of Section 
When welding the valve into line verify that the ball is in the fully
open position (the valve is in the open position when the handle
is parallel to the axis of the valve and pipe) prior to welding to
protect the ball sealing surface from possible damage Ensure
that the piping and valve end connections are properly aligned to
avoid line bind
Apply a welding ground strap adjacent to the valve end being
welded to prevent current flow through the valve
