C seats

❑

Check the sealing surfaces.

❑

Place graphite backseal (129) carefully into the
seat. Make sure the backseal is installed in cor-
rect direction.

❑

Make sure there are not any sharp edges in the
seat cavity of valve body to damage the back-
seal.

❑

Place the seat into the body.  

4.7.2

Bearings and ball

PTFE bearings

❑

Place the bearings (60,61) onto the thrust and
trunnion bearings so that the PTFE surface
touches the stem. See Figure 15.

❑

Push the bearing (60) into the thrust bearing (4).

❑

Turn the bearing (61) so that it fits inside the trun-
nion bearing (5). Push the bearing until the lip is
flush with the flange groove. Then release the
bearing and push the lip into the groove.

❑

When you install the thrust bearing (89), make
sure that the PTFE surface is against the ball
shoulder.

❑

Push the bearings onto the stem and the trun-
nion. 

Heat-resisting bearings

High-tolerance cobolt alloy bushings are used as bear-
ings.

❑

Place the bearing (4) onto the stem so that the
shoulder faces the ball.

❑

Place the trunnion bearing (5) in its place.

Ball

❑

Lower the ball (3) carefully to the female body
half (2). The bearings will ensure that the ball
goes into the correct position inside the body
half. 

4.7.3

Body Joint

Depending on the valve application, the body joint gas-
ket (65) is of either PTFE or graphite. 

   

❑

Place the PTFE gasket into the outer circumfer-
ence of the groove of the female body half. See
Figure 17.
