Bolt bonnet lift plug valve is widely utilized in petroleum, chemical industry, metallurgy, etc. Lift hard seal plug valve can connect or cut off medium in pipelines in case of back flow of medium.
Opening and closing of the valve is carried out while the sealing surface is taken off, so it will not cause abrasion on the sealing surface.
Nominal pressure: Class 150-900Lb
Nominal diameter: 1/2-14 inch
Working principle
When opening the valve, first of all, turn the hand wheel to make the plug lifted and separated with the sealing surface, the turn the handled by 90 degree to connect the channel of plug the channel of valve body. So 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 the valve is closed.
