Butterfly valve for 200 mm pipe diameter (ANSI standart (CL.150LBS)). The lug type soft seated butterfly valve is simple in structure, small in size, light in weight, and has few components on structure. Several key parts can build a butterfly valve, which is also very convenient to open.The butterfly valve can control the fluid very well, and can increase or reduce the flow at any time. The lug type soft seated butterfly valve can be installed by cl amping between two flanges, or installed at the end of pipe out let. The butterfly valve position is fixed through tap thread connection holes. The lug type butterfly valve body can be manufactured to the GB/JB/HG flange standard, ANSI/AS ME flange standard, JIS flange standard and other uncommon or non-standard flange stan dards. The butterfly valve can be controlled in many ways, such as handlever, gear operator, electric actautor, pneumatic actautor and hydraulic actautor. Multiple control requirements can be achiev ed in a variety of ways. The lug type soft seated butterfly valve has short face- to- face length, thin installation space requirements, light weight and high cost- effective, and can be used for switching and flow control of liquid, gas, powder and other media. Soft seated butterfly valve also has a wide range of applications. If they are used to control the flow, different types and valve body sizes need to be selected, because butterfly valves are more suitable for some valves with larger diameters when they are designed. Butterfly valves are not only widely used in petroleum, gas, chemical, water treatment and other general industries, but also used in the cooling water system of thermal power plants.
