Double eccentric telescopic butterfly valve (SDRF)
Double eccentric telescopic butterfly valve (SDRF)
VGZ Double eccentric telescopic butterfly valve (SDRF)（SD342X\SD342H)
| Describe： |  |
|||||
| For the double-eccentricity butterfly valve, when the butterfly plate rotates from 0° to 8°-12°, the butterfly plate sealing face will break away from the valve seat sealing face completely, thus reducing the mechanical abrasion and the extrusion corner travel during opening or closing the butterfly valve. With the reduction of mechanical abrasion and extrusion, the sealing performance and service life of the butterfly valve will be improved greatly. | ||||||
