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. |
