Principle of opening and closing of the valve 
When the valve is fully opened, the channel of plug is in alignment with the channel of valve body, which can ensure ideal and lowest decrease on pressure. When the hand wheel is turned, the plug will rotate toward the closing direction, and make the same time draft the rotation of valve seat and close the valve. When the hand wheel is turned inversely, first of all the plug will move upward, and the valve disc and valve seat will be separated; if the hand wheel is turned further on; till the valve disc is turned by 90 degree driven by the plug, and finally the channel of plug will be in alignment with the channel of valve body, so that the valve is be fully opened.
