API 6D Expanding Gate Valve
API 6D Expanding Gate Valve
| describe： |   |
|||||
| The two sealing faces of a slab gate valve are perpendicular to the pipeline axis, its closing member have double discs, valve equipped with a stretching mechanism. The gate valve is widely applicable for transmission pipeline system of natural gas 、oil products and chemical engineering. | ||||||
| Design features： | ||||||
| Design standard as per: API 6D、ASME B16.34、GB/T 19672 its performances as small operation torque, better sealing, lower noise during operation, safety and reliable operation; The valve disc and valve seat seal are repeatedly treated by special processes, and protected by multiple seals, and featured with anti-corrosion, penetration-proof, anti-abrasion and long service life; Valve seat is designed with hard-soft double seal, having reliable tightness; With a full bore design, both the coefficient of flow resistance and the pressure loss are very small; When the valve is fully opened, medium erosion occurring to its sealing face is smaller than that of other valves; The through conduit gate valve with diversion holes installed on a pipeline can also be cleaned by a pipe cleaner directly; No space restriction on valve installation, that is, both parallel and perpendicular installations are allowed. |
