Knife Gate Valve
/ Installation and Maintenance Instructions
INSTALLING THE 906 VALVE INTO AN HDPE
PIPING SYSTEM
WARNING
• Wear gloves while handling valve. Retainer
teeth are sharp and may cause injury.
• This valve is intended for use on plain-end
HDPE pipe and is NOT to be used on steel
pipe.
Failure to follow these instructions could result
in personal injury, joint leakage, and property
damage, and could void the product warranty.
1a. DO NOT REMOVE OR ADJUST THE ASSEMBLY HARDWARE:
Series 906 Installation-Ready
™
Knife Gate Valves are designed so
that the installer does not need to remove the assembly hardware for
installation . This design facilitates installation by allowing the installer to
directly insert a pipe end into each opening of the valve .
1b. REMOVE SLEEVE:
Remove the cardboard sleeve from the valve
interior .
NOTE:
This cardboard sleeve will be used as a guide for
marking the pipe ends in step 4 .
2. INSPECT PIPE ENDS:
Ensure that the pipe ends are clean and free
from damage and scratches within 2
1/2
inches/64 mm from the ends . All
oil, grease, dirt, and cutting particles must be removed . Failure to do so
will result in difficult assembly and potential joint leakage .
3. INSPECT PIPE GASKETS:
Check the pipe gaskets to ensure that
they are suitable for the intended service . The color code identifies the
gasket grade . Refer to Victaulic publication 05 .01 in the G-100 General
Catalog for the color code chart .
CAUTION
• A compatible lubricant must be used to prevent the pipe gaskets
from pinching/tearing during installation.
• Pipe gaskets are designed for one-time use only. DO NOT
attempt to reuse pipe gaskets.
Failure to follow these instructions will cause gasket degradation,
resulting in joint leakage and property damage.
4.
MARK PIPE:
Using the cardboard sleeve and a paint stick, mark
each HDPE pipe end around the full circumference:
• 1
7/8
inches/48 mm for 2–3-inch pipe sizes
• 2
1/4
inches/57 mm for 4–8-inch pipe sizes
This mark will be used for visual inspection to ensure that the HDPE
pipe is inserted properly in the valve . If a full circumferential mark
cannot be achieved, make at least four marks equally-spaced around
the circumference of each HDPE pipe end .
5. LUBRICATE PIPE END:
Apply a thin coat of lubricant to the pipe
end from the end of the pipe to the paint mark made in step 4 .
Lubricate each pipe end in accordance with the “Lubricant
Compatibility” table . Always consult with the pipe manufacturer for
lubricant compatibility requirements .
