NOTICE
Due to the potential for packing consolidation,
verify proper packing torque adjustment prior to
placing the valve in service. 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.
LOCATE POSITION INDICATORS
The valve operator should be equipped with position
indicators for correct ball bore position.
If position indicators are not visible, the scribe line on
gland flange 07 can be used to determine the position
of the ball bore. When viewed through the mounting
adaptor opening 14, the stem scribe line and gland
flange scribe line should align.
Operation
LOCATE POSITIONAL STOP PINS
The installed operator performs all switching functions
between drums A, B, and BP.
Positional stop pins are used to prevent switching
once a position is selected. All pins and keys are
tethered to the mounting flange via cables.
Note: Positional stops include Bypass (BP) Lock/Stop Pin,
Lockout Pin 1 and Lockout Pin 2.
Secure lock-in pins are provided, and should be
used once lockout pins are engaged into their proper
location.
