LT type is also called a single Plate butterfly valve, lug type butterfly valve. It is a simple structure of the regulating valve. that can be used for low-pressure pipeline medium switching means that the closing element (valve or butterfly plate) is a disk, and rotates around the valve shaft to open and close.
A valve that can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil products, liquid metals. In the pipeline mainly cut off and throttling effect. The butterfly valve opening and closing device is a disc-shaped butterfly plate, rotating around its own axis in the valve body, so as to achieve the purpose of opening and closing or adjusting.
