With the gland wench provided, screw
the gland nut down until it bottoms out.
Do not over-tighten! (Image 15).

the locking screw head, back the gland
nut off further to align (Image 16).

Insert the locking screw after applying a thread locking adhesive (Image 17). Tighten the
locking screw as per the torque values given in table 4.1.
NOTE: Rotate the spindle 1-2 times to ensure the operating torque is constant, and the
rotating action is smooth.
Reassemble and connect the handle kit or actuator to the valve. When connecting to
an actuator, ensure that the valve and actuator are both in the "zero" or starting position
before mounting together.
NOTE: The valve is CLOSED when the spindle notch points to the "0" mark stamped on
the valve top (see Image 17).
