CAUTION!
It is
extremely important
to follow these steps to
ensure maximum valve performance .
THIS WILL AFFECT THE VALVE WARRANTY .
!
VERIFY BOLTING TORQUE
After the first exposure to elevated temperature and
the valve has completely cooled-down, verify bolting
torque at these locations:
1
Packing gland flange
2
Body to end connection
3
Actuator to valve mounting (if present)
Check the bolting at these same locations periodically .
CAUTION!
If bolting torque is lower than specified values on
the
test certificate
provided for each
individual
valve serial number, re-torque bolting as necessary .
THIS WILL AFFECT THE VALVE WARRANTY .
!
OPEN / CLOSE VALVE REGULARLY
Valves remaining
open
or
closed
for a long period of
time should be cycled
open
/
closed
at least once a
year .
Valves should always be
fully opened
and
fully
closed
to wipe away any accumulation on the
sealing surfaces .
ACTUATOR LUBRICATION
Keep hydraulic, pneumatic and worm gear actuators
fully lubricated according to actuator manufacturer’s
specifications .
