Structures and Various Classifications of Valves

The 2PC Ball Valve has an opening and closing function. It is mainly composed of a valve body, opening and closing part and the valve lid. The basic parameter of the valve is working pressure, working temperature and caliber. Various valves which are used in the industry usually use the nominal pressure and nominal diameter as the basic parameters. According to different requirements, valve can be divided into different types.

According to the function and use, the 2PC Ball Valve MF supplier can be divided into cut-off valve, check valve, safe value, regulating valve and the shunt valve. The truncation valve is mainly used for cutting fluid pathway. It includes cut-off valve, gate valve, plug valve, ball valve, butterfly valve, diaphragm valve, pinch valve and so on. The flanged ball valve and floating ball valve belong to the ball valve. The stainless steel check valve is used for preventing the reverse flow of fluid. Safety valve is mainly used for security protection, and prevents the boiler, pressure vessel or pipes from damaging because of the overpressure. Regulating valve is mainly used for regulating fluid pressure and flow rate, including a regulating valve, throttle valve, pressure reducing valve and floating ball regulating valve and so on. Shunt valve includes a distribution valve and a drain valve; its role is assigning, separating or mixing the media in the pipe.

Based on the nominal pressure, the 3PC Ball Valve BW can be divided into vacuum valve, low pressure valve, medium voltage valve, high pressure valve and super high pressure valve.

According to the driving method, the valve can be divided into automatic valve, power driven valve and manual valve. Automatic valve doesn't need the outside force drive, while relies on the media's own energy to make the valve the valve act. Power driven valve can use a variety of power source to drive. Manual valve relies on the people to operate the valve with the help of the hand wheel, handle valve, lever and sprocket.

According to the connection method, the valve can be divided into the thread connection 1PC Wafer Flanged Ball Valve , the flange connection value, welding connection valve, the clamp connection valve, the card set connection valve and the double-clip connected valve. The valve body of the flange connection includes the stainless steel flanges, and connecting the flange connection valve and the pipe flange.

The valves manufacturing industry is very developed, and develops continuously. To sum up, the valve classification method is very much, but the main classification method is based on the function in the pipeline.
