®
Three-Piece Carbon Steel and
Stainless Steel Ball Valves
Read carefully before attempting to install, operate, maintain or disassemble this valve. Protect
yourself and others by observing all safety information.
WARNING
For your safety, it is important that the following precautions be taken prior to installation, any
servicing or removal of the valve from the line or before any disassembly:
1. At all times during this entire procedure, keep hands out of the valve. A remotely
actuated valve could close at any time and result in serious injury.
2. This valve must be installed in accordance with all applicable power piping standards
(ANSI B31.1) and all local codes.
3. Consideration should be given to the placement and position of the valve when
installing. The valve should be positioned in such a manner that the handle will not
be bumped or snagged and inadvertently operate the valve.
4. For applications having elevated temperatures (over 100°F) refer to the
pressure/temperature performance curves published in the catalog to determine the
maximum safe working pressure for the seat material. Do not exceed this rating.
5. Wear all protective equipment normally required to guard against discharge of
trapped fluid before attempting to remove or disassemble this valve.
6. Do not attempt to remove or disassemble this valve while it is under pressure.
Depressurize the line and valve as follows: Place the valve in the open position and
drain the line. Cycle the valve to relieve pressure trapped in the body cavity. After
removal and before disassembly, cycle the valve several times.
INSTALLATION
The following procedures will aid you in the installation, please follow them carefully:
1. THREADED
BODY ENDS:
Use standard piping practices when installing valve. To prevent damage to the valve when
tightening valve to pipe, apply wrench to the body end (11) nearest the pipe being tightened.
