◆ Product Overview Chain principle of eccentric butterfly valve is used in 3 d design,is based on the original double eccentric added a unique eccentric, not only use the original CAM effect, and completely eliminated the rotate 90 degrees in the friction between the valve plate and seal completely.By optimizing the contact Angle between the butterfly plate seal face and seat sealing characteristics of contact Angle is greater than the lock valve cone Angle range. From the geometric shapes,ruled out the possibility of a butterfly card by death,to ensure that the valve switch required torque.
