1、敞开式直通流道，流阻小，高效节能。 2、单座双密封结构，无内腔升压问题。 3、启闭迅速，90。回转，力矩小，操作轻决。 4、偏心结构，启闭无磨损，自动补尝密封，使用寿命长。 5、高硬度密封面，能解决管路中颗粒、纤维、结垢沉淀等各种问题。 6、可采用各种材质密封面，适用于各种工况，各种介质。 7、体积小，重量轻，结构简单，安装方便，易于维护检修。 |
1.Open
straight-through channel with low flow resistance, high efficiency and energy
saving. 2. SingIe-seat double sealing由ucture has no pnmire increase problem in cavity. 3. Rapid open and close. Small 90’ flywheel moment makes the operation easy. 4. Eccentricity structure. No abrasion when open and close.Automatically compensate the seal and have long service period. 5. High rigidity sealing aufaoe can settle various problems inducting particles, fibre and fouling sedimentationmpipeline. 6. Can adopt various material sealing surface for various work 溢住ration and media. 7. Small volumie, light weight, simple stnrcture and easy installation, convenient. maintenance and overhauls. |
