Australian Pipeline Valve - Installation, Operation and Maintenance Manual
6
BALL VALVES - FS900 SERIES
2.1 PREPARATION FOR INSTALLATION
• Remove protective end caps or plugs and inspect valve ends for damage to threads.
• Thoroughly clean adjacent piping system to remove any foreign material that could cause damage to
seating surfaces during valve operation.
• Verify that the space available for installation is adequate to allow the valve to be installed and to be
operated.
Ensure sufficient clearance for the stem in the full open position. Inadequate
clearance for valves may add mechanical loading to the valve ends. Sufficient
clearance should be allowed for threaded end valves to be ‘swung’ during
installation.
2.2 END CONNECTIONS
2.2.1 Threaded Ends
Check condition of threads on mating pipe. Apply joint compound to the male end of joint only. This will
prevent compound from entering the valve flow path. Use compatible grade of PTFE thread tape.
FS900 Series is not suitable for socket weld use.

3.1 MANUAL OPERATION
Valve adjustment is by clockwise turning of stem. Lever operated valves have a position indicator to
indicate open or closed (see figure 1). Ball Valves must not be used for throttling. Do not leave part open,
or seats will be damaged. Valve must be full open or full closed or damage to seats or body will occur.
