Final Cleaning and Recording of Damage 

After dismantling all parts are finally cleaned. The dismantled sealing parts are also to be included in cleaning so 
that they may be disposed of with problem. 
The damage is then recorded. 
Special attention must be paid to inside and outside damage to the body parts. The nature of the sealing surfaces 
at the ball seal, stem conduit, body sealing and the flange seals must be checked. The body parts are then jet-
cleaned inside and out with glass pearls and cleaned mechanically if necessary and possible. For this purpose 
sealing areas must be covered up. 
The valves are then to be cleaned anew and are then available for a further visual check for new assembly. 
The stem is checked after visual checking for parallel running and traces of pressure of the two other flanges. 
Special attention must be directed at the perfect state of the sealing areas. Slight scratches can be removed with 
emery cloth. Damaged or twisted stems are replaced. 
The cleaned ball is firstly visually checked. Deep scratches as well as other mechanical damage and chemical 
attack on the sealing surface as well as the running surface of the seal ring mean that the ball must be discarded. 
Similarly deformation in the area of the ball slit is inadmissible. All screws and sealing parts must be replaced 
during every repair.
