I. INSPECTION
1. Operate all valves, fully opened and closed, before installing to ensure
functionality.
II. THREADED INSTALLATION PROCEDURES
1. Assure the valve is suitable for service to which it is being applied. Contact
NIBCO Technical Services with any concerns or questions: [phone].
2. To ensure proper installation, standard piping practices should be followed.
3. NIBCO 2-piece ball valves are bi-directional service valves and can be installed
in any orientation, vertically or horizontally.
4. Check connecting pipe threads are free of foreign materials such as scale or
metal shavings, as well as in proper and functioning form.
5. Apply 2-3 wraps of PTFE tape, covering the lower ¾ of the male thread length in
a clockwise direction as viewed from the threaded end of the male pipe.
WARNING: NIBCO does not recommend applying pipe compound on threaded
joints, and under no circumstance should both PTFE tape and pipe
compound be applied to any threaded joint.
6. Hand tighten pipe into valve.
7. Use a flat-jawed wrench (adjustable) to engage the flats of the valve. If a pipe
wrench is used, it must be applied only to the pipe, not the valve.
8. Do not apply excessive torque to assemble the joint. As a rule of thumb, tighten
(2) turns past hand tight.
9. Follow all other applicable and appropriate code requirements.
III. SOLDERING INSTALLATION INSTRUCTIONS – LEAD-FREE* BRASS*/PERFORMANCE
BRONZE
®
* BALL VALVES
NOTE: NIBCO ball valves can be soft soldered into lines using a low temperature solder such
as 95/5 tin antimony solder which melts at 452° - 464°F. For all lead-free solders
which melt in this temperature range, extreme care must be used to prevent seat
damage since temperatures above 500°F will affect the seat materials.
**For instructions on soldering NIBCO lead-free* Performance Bronze™ alloys see
the latest edition of NIBCO Technical Bulletin NTB-0910 (www.nibco.com) or contact

1. To ensure proper installation, standard piping practices should be followed,
including ASTM B828.
2. Clean and flux the surfaces to be soldered.
3. Close the valve. This does two things – it gets the handle out of the way and protects
the PTFE seats from cold-flowing during heating by trapping them against the ball.
4. With the flame directed away from the valve, apply heat to the end opposite the
threaded end piece. Apply solder and move off.
