Reassembly
Cameron recommends replacement of all soft parts whenever the valve is disassembled for reconditioning.
• Lightly grease the thrust washer (05), the stem seal area, and the threads of the stem. Insert thrust washer
(05) into the body shoulder.
• Insert stem (11) up through the body cavity, through the thrust washer (05) and body stem bore. Make sure
the stem shoulder is firmly against the thrust washer (05) to where the stem is extended out of the top of the
body as far as possible.
• Press the body seals (16) into the grooves of each cap (03).
• Turn the stem (11) to a position with the ball/stem tang flats parallel to the cavity.
• Before installing the ball, make a visual inspection for any nicks, scratches, pitting or corrosion. Install the
ball (02) into the body (01), lining up the ball slot with the stem drive tang. The ball should be in the
closed position.
• Rotate ball (02) to the open position.
• Install joint gaskets (06) for each side of the body (01).
• Apply grease to the face of each seat (06) and simultaneously press seats into i.d. of the body bore and joint
gaskets (06) until contact is made with the ball.
• Carefully, avoiding damage to the seats and seals during assembly, swing valve body section back into posi-
tion while holding the seats and gaskets in place.
• Install and hand tighten all body bolts (09) and washers (08).
• Carefully install packing (7) over stem and press down into the counter bore of the body top pad.
