Relative Introduction and History of Valves

The valve products are produced with the production of fluid pipes. It has been a long history that people used 2PC Ball Valve MF supplier for 4000 years. The ancient Egyptians used a similar wooden cock to control the allocation of water when they built large-scale water conservancy to prevent Nile flood before 1800BC. The wooden cock is the prototype of the valve. The valves are used for industry in large scale when Watt invented the steam engine. At the beginning of 20th century, valve products made of cast iron, cast steel, forged steel, stainless steel, chrome-molybdenum steel, brass and other materials were produced, and they are used for a lot of fields for various working conditions. 

The ball valve with vertical mounting pad are the devices used for controlling the directions, pressures and flow of the fluid in a fluid system. The valves are the equipment used for controlling the flow and stop of the media such as liquid, gas or powder in the pipes or devices. The inox valves have been developed by the valve factory into the valve products including plug valves, gate valves, globe valves and 3 pc ball valve. 

The valve products are the controlling components in the fluid delivery system of the pipeline, and they are used for changing the passage cross-section and the flow direction of medium. The 2PC Ball Valve MF have the functions of flow guidance, throttling, returning resistance, flow bypassing, pressure reducing for overflowing, etc. The valves used for controlling the flow come in the simplest stop valves to the most complicated valves which are used in the self-control systems. The inox valves come in a variety of categories and specifications. The inside nominal diameters of the valves are different, and the valves can include tin instrument valves and industrial used pipe valves of 10m diameter. The valves can be used for controlling water, steam, oil products, gases, mud, various corrosive media, melted metal, radioactive fluid and other types of fluids. The working pressure of the 1PC Wafer Flanged Ball Valve (DIN) can be 0.0013MPa 1000MPa, and the working pressure of the valves can be as low as -260 Celsius degree and can be as high as 143 Celsius degree. 

The controlling modes of the inox valves can be realized through many transmission modes including manual mode, electric mode, hydraulic mode, pneumatic mode, turbine mode, electromagnetic mode, electromagnetic hydraulic mode, electric hydraulic mode, pneumatic hydraulic mode, spur gear mode, bevel gear drive mode, etc. The valves can simply open and close according to the transmission signals of pressure, temperature, etc.
