3. If replacement of the ball, shafts (keys 6 or 9), or bearings (key 10) is needed, proceed to the Bearing and Ball
Maintenance procedure. If only the seal is to be replaced, proceed to the Installing HD Metal Seals section.
Installing HD Metal Seals
Refer to figures 6, 14, and 15 for key number locations during seal installation.
Thoroughly clean all parts that are to be re‐used and obtain replacement parts. Be sure that all sealing surfaces are in
good condition without scratches or wear. If the valve has been installed between line flanges and the flange studs and
nuts have been tightened, always replace the gasket (key 15) with a new gasket.
1. For
DN 80 and 100 (NPS 3 and 4),
before installing HD metal seals, ensure ball (key 2) is installed into valve body.
Ball should be in closed position while you install the seal and seal protector ring. Insert a screwdriver, pry bar, or
similar tool between the lower ear of the ball and the valve body (see figure 5).
2. Use the pry to move the ball tightly against the bearing on the actuator side of the valve. Be careful, excessive force
may damage the ball. Keep the ball in that position until you have completed seal or flow ring installation. Check
the ball's position periodically, and re‐center if necessary, during lever assembly and packing adjustments. See
figure 5.
WARNING
The Vee‐Ball closes with a shearing, cutting motion, which could result in personal injury. To avoid injury or property
damage, keep hands, tools, and other objects away from the Vee‐Ball while stroking the valve.
3. Lubricate and install the radial seal (key 37) into the appropriate groove in the seal protector ring making sure the
open side of the radial seal faces away from the ball.
4. Install the wave spring (key 13) into the seal protector ring (key 3).
