GENERAL
1.1
Scope of the Manual
This instruction manual contains important information
regarding the installation, operation and maintenance of
the Jamesbury® ½” - 2” (DN15-50) ASME Class 150 & 300
Full Bore; Series 6000 and ½” – 1 ½” (DN15-40) ASME Class
150 & 300 Standard Bore; Series 5000 Flanged Ball Valves;
Models B & C. 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:
DOUBLE-SEATED BALL VALVE DESIGNS, LIKE THE SERIES 5000, CAN
UNDER CERTAIN CONDITIONS TRAP FLUID IN THE BALL CAVITY.
RAISING THE TEMPERATURE OF THE TRAPPED FLUID CAUSES THE
INTERNAL VALVE PRESSURE TO RISE. EXTREME TEMPERATURE
RISE CAN BUILD UP EXCESSIVE PRESSURE WHICH COULD LEAD
TO UNCONTROLLED PRESSURE RELEASE. DAMAGE OR PERSONAL
INJURY MAY RESULT.
1.2

Safety Precautions
WARNING:
DO NOT EXCEED THE VALVE PERFORMANCE LIMITATIONS!
EXCEEDING THE PRESSURE OR TEMPERATURE LIMITATIONS
MARKED ON THE VALVE IDENTIFICATION PLATE MAY CAUSE
DAMAGE AND LEAD TO UNCONTROLLED PRESSURE RELEASE,
DAMAGE OR PERSONAL INJURY MAY RESULT.
WARNING:
SEAT AND BODY RATINGS!
THE PRACTICAL AND SAFE USE OF THIS PRODUCT IS
DETERMINED BY BOTH THE SEAT AND BODY RATINGS. READ
THE IDENTIFICATION PLATE AND CHECK BOTH RATINGS. THIS
PRODUCT IS AVAILABLE WITH A VARIETY OF SEAT MATERIALS.
SOME OF THE SEAT MATERIALS HAVE PRESSURE RATINGS THAT
ARE LESS THAN THE BODY RATINGS. ALL OF THE BODY AND
SEAT RATINGS ARE DEPENDENT ON VALVE TYPE AND SIZE, SEAT
MATERIAL, AND TEMPERATURE. DO NOT EXCEED THESE RATINGS!
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 PIPELINE. WHEN THE VALVE IS ACTUATED,
THE BALL FUNCTIONS AS A CUTTING DEVISE. DISCONNECT ANY
PNEUMATIC SUPPLY LINES, ANY ELECTRICAL POWER SOURCES AND
MAKE SURE SPRINGS IN SPRING-RETURN ACTUATORS ARE IN THE
FULL EXTENDED/RELAXED STATE BEFORE PERFORMING ANY VALVE
MAINTENANCE. FAILURE TO DO THIS MAY RESULT IN DAMAGE OR
PERSONAL INJURY!
WARNING:
WHEN HANDLING THE VALVE OR VALVE/ACTUATOR ASSEMBLY,
TAKE ITS WEIGHT INTO ACCOUNT!
NEVER LIFT THE VALVE OR VALVE/ACTUATOR ASSEMBLY BY THE
ACTUATOR, POSITIONER, LIMIT SWITCH OR THEIR PIPING. PLACE
LIFTING DEVICES SECURELY AROUND THE VALVE BODY. FAILURE
TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN DAMAGE OR
PERSONAL INJURY FROM FALLING PARTS (SEE FIGURE 2).
