High Performance Butterfly Valve


CEPAI high performance butterfly valve is adopted three-eccentric
structure which has the characteristics of good controlling and cutting off
performance, long service life, wide applicable temperature range and
convenient maintenance.
The configuration designed with principle of three-dimensional eccentric
makes the movement tracking perfect and no friction between sealing
pair, no intervenes between hermetical components. Choosing the right
sealing material to ensure the sealing performance, corrosion resistance,
high temperature and wear resistance are reliable.

Design Features
· Small torque of opening and closing, flexible and saving energy
· Three-dimensional eccentric makes the disc tighter and tighter when it closed
· Multiple layers plug structure for wide range applications
· Characteristics of high temperature, high pressure and corrosive resistance
· Torque sealing to ensure persistent two-way zero leakage
· Right angle rotation with zero friction is implemented by the seat and sealing in 90°
· Anti blowing out stem for high dependability, completely conforming to API 609
· Fire proof conforming to API 607
