Revisions, repairs and conversions

Our many years of experience in the field of ball valves with diameters from 25 to 2,600 mm (DN 1" - 104") enable us to apply our expertise in the maintenance and repair of ball valves, even during plant operation.

In addition, we offer the production of spare parts, such as ball and seat rings using special ball and vertical lathes.

Valves severely damaged by corrosion are refurbished by cladding and hardfacing sealing surfaces including respective PWHT measures in such a way that they are equivalent to new fittings.

In addition, safety valves, control valves, slides, flaps and drives can be repaired, refurbished and even modified at the Gladbeck plant for all manufacturers. For modifications and improvements we feature supports made of PEEK (Polyether ether ketone), replacing conventional sealing rings by U shaped rings with preloaded springs or substituting tongue springs by compressed spring types. In some cases, existing ball valves can also be upgraded to "fire safe".
