Center Line-type Butterfly Valve

Technical dataSpecification:DN50-DN2600Nominal pressure: PN10/PN16Working temperature: -10℃～150℃Suitable medium: Water, sewage, seawater, gas, food, oil and so on.Connection Mode: Flange ModeProduct 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 lifeand 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 inclosing. 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 discdoes 90°degree rotation. Opening and closing of disc is flexible without jam and beat; torque is small.
