5. Repeat step 4 on threaded insert end.
6. Upon completion of steps 1 – 5, leave the valve in the closed position until cool.
7. Heat from soldering, if excessive, may affect PTFE stem packing. After completion of
soldering, it may be necessary to tighten packing gland. Always check for leakage after
installation.
WARNING: DO NOT under any circumstances, solder the downstream end of this valve
while there is upstream pressure/or with fluid trapped in the cavity around
the ball. Thermal expansion of this fluid could produce excessive internal
pressure which could damage seat or body materials. Always drain down
the system and cycle the valve two to three times after drain down is
complete before applying heat. Steam created from trapped fluid in cavity
around the ball could cause the valve to burst if valve is heated excessively.

IV. PRESS INSTALLATION PROCEDURES
1. Please refer to NIBCO Press System catalog for instructions on connecting Press-
ended valve to piping system.
V. REVERSING HANDLE DIRECTION
1. All 585HP ball valves feature a threaded handle stop
which can be removed and reinstalled in opposite
threaded handle stop location, allowing for reversal of
handle swing direction to avoid contact with
surroundings.
2. Handle stop installation torque and hex drive sizes can
be found in Table 1.
VI. THROTTLING SERVICE
Ball valves are generally not recommended for modulating service where critical flow
rates are required. Contact NIBCO Technical Services for throttling service
applications.
CAUTION: Throttling any ball valves is not recommended, where the valve is less
than 45° open.
VII. MAINTENANCE
1. Valves must be exercised from fully opened to fully closed periodically to assure
continued function. NIBCO recommends valves be put on a routine, periodic
exercise program, such as cycling at least once every 6 months.
2. There are no field repairable or replaceable components within the pressure
vessel of a NIBCO 2-piece ball valve.
WARNING: Under no circumstances should the pressure vessel be
disassembled for any reason, including to attempt internal repairs.
