1.1 Scope of the Manual
This instruction manual contains important information
regarding the installation, operation and maintenance of
the Jamesbury 1/2” – 2” (DN 15 – 50) Series 4000 3 Piece
Ball Valves. Please read these instructions carefully and save
them for future reference.
WARNING:
AS THE USE OF THE VALVE IS APPLICATION SPECIFIC, A NUMBER
OF FACTORS SHOULD BE TAKEN INTO ACCOUNT WHEN SELECTING
A VALVE FOR A GIVEN APPLICATION. THEREFORE, SOME OF THE
SITUATIONS IN WHICH THE VALVES ARE USED ARE OUTSIDE THE
SCOPE OF THIS MANUAL.
IF YOU HAVE ANY QUESTIONS CONCERNING THE USE, APPLICATION
OR COMPATIBILITY OF THE VALVE WITH THE INTENDED SERVICE,
CONTACT METSO FOR MORE INFORMATION.
WARNING:
BEWARE OF BALL MOVEMENT!
KEEP HANDS, OTHER PARTS OF THE BODY, TOOLS AND OTHER
OBJECTS OUT OF THE OPEN FLOW PORT. LEAVE NO FOREIGN
OBJECTS INSIDE THE VALVE. WHEN THE VALVE IS ACTUATED, THE
BALL FUNCTIONS AS A CUTTING DEVISE. FAILURE TO DO THIS MAY
RESULT IN DAMAGE OR PERSONAL INJURY!
1.2 Safety Precautions
WARNING:
VALVE RATINGS!
THE PRACTICAL AND SAFE USE OF THIS PRODUCT IS DETERMINED
BY BOTH THE CWP RATINGS: CAREFULLY CHECK RATING. THIS IS
THE SAFE USE PRESSURE FOR THIS VALVE BETWEEN 20 TO +100F
29 TO +38C. DO NOT EXCEED THESE RATINGS! FOR INSTALLATION
TEMPERATURES BELOW AND ABOVE THESE LIMITS CONTACT METSO.
2. TRANSPORTATION AND STORAGE
Check the valve for any damage that may have occurred
during transport.
Store the valve carefully. Storage indoors in a dry place is
recommended.
Do not remove the ow port protectors until installing the
valve.
Move the valve to its intended location just before installation.
The valve is usually delivered in the open position.
If the valve(s) are to be stored for a long duration, follow the
recommendations of IMO-S1.
3. INSTALLATION
3.1 General
Remove the protective packaging and ow port protectors and
check that the valve is clean inside. Clean valve if necessary.
Flush the pipeline carefully before installing the valve.
Foreign objects, such as sand or pieces of welding electrodes,
will damage the ball and seats.
Read and follow all WARNINGS!
Refer to the Section 4, MAINTENANCE for stem seal
adjustment. If there is weepage past the stem seals upon
installation, it means the valve may have been subject to wide
temperature variations in shipment. Leak-tight performance
will be restored by a simple stem seal adjustment described
in the MAINTENANCE section.
1. Screwed End Style - Screwed end valves have NPT
threads. To insure a leak tight joint, liberal use of a
compatible pipe joint compound is necessary. Use
standard piping practices to install valves with threaded
end caps. When tightening valve to pipe, apply wrench
to end cap nearest the pipe being worked.
2. Weld End Style - All standard weld end valves must be
partially disassembled prior to welding. Follow Steps 1,
2, 4 and 5 of DISASSEMBLY Section. Socket weld ends
are per ANSI B16.11 and butt weld ends are per ANSI
B16.25. Welding should be done using procedures and
welders qualied under Section IX of the ASME Boiler
and Pressure Vessel Code. IMPORTANT: If the body
seals (6) are removed for welding, DO NOT MIX THEM.
When reassembling the valve, put each seal back into
the groove from which it was removed.
CAUTION: IF THE VALVE IS BEING DISASSEMBLED FOR
WELDING. DO NOT CUT OR SCRATCH THE SEATS, SEALS
AND SEALING SURFACES.
3. After valve is in line, or before testing, tighten stem nuts
(16) per the MAINTENANCE Section below.
WARNING:
FOR YOUR SAFETY IT IS IMPORTANT THE FOLLOWING PRECAUTIONS
BE TAKEN PRIOR TO INSTALLATION, SERVICING OR REMOVAL OF
THE VALVE FROM THE PIPELINE OR BEFORE ANY DISASSEMBLY:
1. WEAR ANY PROTECTIVE CLOTHING OR EQUIPMENT NORMALLY
REQUIRED WHEN WORKING WITH THE FLUID INVOLVED.
2. DEPRESSURIZE THE PIPELINE AND CYCLE THE VALVE AS FOLLOWS:
A. PLACE THE VALVE IN THE OPEN POSITION AND DRAIN THE
PIPELINE.
B. CYCLE THE VALVE TO RELIEVE RESIDUAL PRESSURE IN THE
BODY CAVITY BEFORE REMOVAL FROM THE PIPELINE.
C. AFTER REMOVAL AND BEFORE ANY DISASSEMBLY, CYCLE
THE VALVE AGAIN SEVERAL TIMES.
3. THESE VALVES ARE SUITABLE FOR A WIDE VARIETY OF
FLUIDS AND GASES. BE CERTAIN THAT THE VALVE MATERIALS
SELECTED ARE SUITABLE FOR THE APPLICATION.
