Features:
1, reasonable structure, light weight, flexible operation and reliable sealing.
2, the butterfly valve adopts three eccentric structure, the sealing surface adopts oblique cone form, and the valve seal force is transferred from the stem torque to the oblique cone surface.The force is formed, and the reasonable design eliminates the contact friction between the valve plate axial sealing surface and the valve seat, avoids friction imitation, and closes more tightly when closing, and the sealing is reliable.After opening, the sealing pair is completely out of contact, making valve life longer.
3, the sealing pair is all metal structure, it has corrosion resistance, high temperature resistance, wear resistance and wide application range. |
