3. The seal can be removed through the outlet end of the valve. In NPS 6x8 and larger valves there is room to
manipulate the seal around the ball and remove it from the outlet end. Remove the wave spring (key 13), and the
radial seal (key 37).
4. 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.
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.
