Lift Plug Valve
Lift plug valves - Structural Features
Lift plug valve is applicable to the cutting and connection of pipelines medium that are used in various industries such as petroleum, chemical industry, pharmacy, chemical fertilizer, power industry etc under nominal pressure of ClASS150-1500lBS,and working temperature of-29-550’C.
- The product has reasonable structure, reliable sealing, excellent performance and beautiful appearnce.
- Opening and closing of the valve is carride out while the sealed surface is taken off, so it will not cause abrasion on the sealed surface.
- Its characteristic double-direction flow makes installation and use more convenient.
- The materials of the parts and sizes of flanges can be reasonably configured according the actual operation condition of the requieements of the customersm, so as to meet the various needs of engineering.
Process of opening and closing of the valve
When opening the valve, first of all, turn the hand wheel to make the plug lifted and separated with the sealed surface, the turn the handle by 90 degree to connect the channel of plug to the channel of valve body, so that the valve is opened; when closing the valve, first of all, turn the handle by 90degree to make the channel of plug vertical to the channel of valve body and then turn the hand wheel to descend the plug, so that the valve is closed.
