Two-Piece Bronze Ball Valves 400 CWP
(Figure 580)
INSTALLATION
1. Operate valve before installing. This verifies functionality.
2. Threaded Valves: Check connecting pipe threads for accuracy. Make sure the pipe
threads are free of foreign materials such as scale or metal shavings.
Soldered Valves: See Installation Bulletin on Page 2.
3. To ensure proper installation, standard piping practices should be followed.
4. The NIBCO two-piece ball valve is a bi-directional valve.
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.
The handle nut also provides the packing preload on the 580 ball valve. When
leakage occurs, the packing/handle nut should be tightened in 1/8 to 1/4 turn
increments just enough to stop leakage.
NIBCO DOES NOT RECOMMEND DISASSEMBLY OF THIS VALVE
TO ATTEMPT INTERNAL REPAIRS.
