Installing HD metal seals
Refer to figures 6, and 13 for key number locations during seal installation.
Thoroughly clean all parts that are to be reused and obtain replacement parts. Be sure that all sealing surfaces are in
good condition without scratches or wear. Place the valve body on a flat surface with the inlet side of the valve facing
up.
1. Lubricate the radial seal (key 37) and install into the appropriate groove in the valve body, making sure the open
side of the radial seal faces away from the ball.
2. Install the wave spring (key 13) into t he appropriate groove in the valve body.
3. HDMetalSealLubricationwill assist with break-in of the HD metal seals and with assembly. It is required that both
the ball surface and seal be lubricated with dry film lubricant or equivalent moly disulfide.
4. Positionthevalvebodyonaflatsurfacewiththeoutletsideofthevalvefacingup.
a. On all sizes without the ball installed, the HD seal can be installed by pushing the HD seal past the wave spring
and radial seal, making sure the HD metal seal remains level. Following this, install the remaining trim
components as explained under the Bearing and Ball Maintenance section and specifically the Assembly heading
on page 13.
b. On NPS 6x8 and larger valves, if the ball is still installed, rotate the ball past the 90 degree open position and hold

side-to-side centering of the ball (key 2) on the seal (key 11). See figure 4.
6. Be sure that the HD seal is fully installed in the valve. Carefully rotate the ball to engage the HD seal while applying
force across the middle of the seal to compress the wave spring until the ball is fully engaged. Be cautious during
this process, knowing that excessive force may damage the ball. Keep the ball in the engaged position going
forward.
7. Continue to check the ball's position and re-center if necessary during actuator mounting and packing adjustments.
