Center Line-type Butterfly Valve

Product Detail

Technical data
Specification:DN50-DN2600
Nominal pressure: PN10/PN16
Working temperature: -10?~150?
Suitable medium: Water, sewage, seawater, gas, food, oil and so on.
Connection Mode: Flange Mode

Product Features: This valve is mainly formed by body, disc, stem, seat and actuator device. 
It has 90°degree quick on-off operation, minimized operating torque which is handy and energy-saving.
Vulcanized seat coated on body can separate body and medium completely. It has long service life
and is suitable to be used in harsh working conditions, and it bears bi-directional pressure in closing 
with no leakage. Its flow curve is tending to straight line and its regulation performance is excellent.
Sealing Performance: Valve is soft sealed and its sealing performance of disc and seat is excellent in
closing. Bi-directional seal performs well; torque is small; 100% no leakage can be ensured under working 
pressure and friction is small between disc and seat (rubber lining). Stem drives disc in valve and disc
does 90°degree rotation. Opening and closing of disc is flexible without jam and beat; torque is small.
