Installation and Maintenance Guidelines for
NIBCO
®
Two-Piece Steel Ball Valves
I. INSTALLATION
1. Operate valve before installing. This verifies functionality.
2. Check connecting pipe threads for accuracy. Make sure the pipe threads are free of
foreign materials such as scale or metal shavings.
3. To ensure proper installation, standard piping practices should be followed.
4. The NIBCO two-piece ball valve is a bi-directional valve.
II. MAINTENANCE
1. General maintenance should consist of operating the valve periodically to ensure
that it is functioning properly.
2. Routine maintenance consists of tightening the packing to compensate for wear.
When leakage occurs, the packing gland follower (under handle) should be tightened
in 1/8 to 1/4 turn increments just enough to stop leakage. This can be done with a
thin open-ended wrench.
NIBCO DOES NOT RECOMMEND DISASSEMBLY OF THIS VALVE
TO ATTEMPT INTERNAL REPAIRS.
