ANSI Flange connection lifting 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 CLASS150~1500LB, and working temperature of -29~550 celsius degree.
The product has reasonable structure,reliable sealing,excellent performance and beautiful appearance.
Opening and closing of the valve is carried out while the sealed surface is taken off,so it will not cause abrasion on the sealed surface.
Its characteristic bi-direction flow makes installation and use more convenient.
The materials of the pars and sizes of flanges can be reasonably configured according to the actual operation condition of the requirements of the customers,so as to meet the various needs of engineering.
Opening and closing of the valve is carried out while the sealed surface is taken off, so it will not cause abrasion on the sealed surface. Double direction.
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 handled by 90 degree to connect the channel of plug the channel of valve body. So that the valve is opened. When closing the valve, first of all turn the handle by 90 degree to mark the channel of plug vertical to the channel of valve body, and then the hand wheel to descend the plug. So that the valve is closed.
