2. If they do not agree, disc must be rotated in the direction of
the larger dimension. If the 3 o’clock dimension is larger, the
disc is not fully closed, and must be rotated in the “close”
direction more. If 9 o’clock dimension is larger, disc is over-
closed, and must be opened slightly.
3. The valve disc is at the full open position when the disc is
perpendicular to the body. Set the “open” actuator stop for
this position. Do not allow the valve to over-open as this
may damage the disc seating surfaces by hitting body or
attached piping.
4. On gear operators, loosen and adjust the closing stop screw
to permit proper disc positioning. Adjust and lock down when
disc closure is within measured tolerance in paragraph
1. Open and close valve; recheck measurements before
reinstalling in line.
5. For other power actuators, consult the manufacturer’s
instructions for setting travel stops, as these vary with
actuator model and type.
6. If removing the valve from the line is not practical, as a crude
remedy the disc can be placed into a position in the seat at
which the leakage stops and travel stops are adjusted to this
position.
