The program controlled butterfly valve with high performance designed and developed by CTYC introduces a triple eccentric structure so that these valves are characterized by zero sealing friction, long sealing life, short action period and are widely used in PSA units. The third generation thereof has come into being. These valves are continuously improved and developed during application, so their structure,
Material and performance have reached a very high level. In recent years, they have been used in the fields for petrochemical, chemical, steel, etc...
