· Brief introduction
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...
· Performances and features
*it is of good sealing performance, with zero leakage.
*it is of quick switching and on-off time can be adjusted.
*it is of long service life, which can withstand long period of frequently on-off.
*it can be applied in adverse circumstances containing combustible, explosive and poisonus matters and dusts like hydrogen, carbon monoxide, etc.
*it is reversible pressure-resistance and the resistance to high-speed gas-flow scouring.
*Automatic switch(i. e. Pneumatic or electric, hydraulic) is provided, it is of adjusting function and site indication of valve position state as well as stitching signal feedback.
