  • the present invention relates to a valve processing apparatus and a method of processing a valve using such a valve processing apparatus.
  • Valves such as those used in power plant technology or in the chemical industry, have different areas that need to be subjected to machining or manufacturing during repair. These include the valve seats and sealing strips, to name just a few examples. When machining, conventional CNC machining centers are usually used, which can be adapted to the specific requirements of valve machining.
  • valve to be repaired must first be removed from the corresponding system. Then it is transported to the valve processing device, stretched in this and edited. In advance, welding work can be carried out on the valve, in particular hardfacing, if a material application is required for the repair work. These can be done either manually or in a corresponding welding device. After checking the processing result, the valve is then transported back to the place of use and mounted. The system can then be put back into operation.
