The choice are braided, V-rings, Cone Shaped, Wedge Shaped etc. The used of one type is depends on the valve packing system. Valve packing system means a complete set of packing that contain one or more packing type to get the seal performance as high as possible and also to fulfill the seal requirement. There are a lot of seal specialist manufacturer that have cooperation with valve vendor to create a good sealing system.

As default packing type or packing system, we could specify it on control valve datasheet as manufacture standard. Since, every particular packing system have its own purposes the valve manufacturer will select the appropriate packing system as per our requirements. 

For example, a SafeGuard Packing System from flowserve is designed to meet the API 607 fire safety requirements. This packing system will stand in the event of a fire even if the primary packing set rendered useless by excessive heat.
