Brief Introduction of Valve
Valves are widely used mechanical products in economic development. They are control devices for fluid pipelines, and their basic functions include connecting or cutting off the flow of pipeline media, changing the flow direction of the media, preventing backflow, regulating the pressure and flow of the media, diverting or overflow relief, and protecting the normal operation of pipeline equipment.

Valves used for fluid control range from the simplest shut-off devices to extremely complex automatic control systems, with a wide variety of types and specifications. Valve specifications range from a few millimeters for instrument valves to industrial pipeline valves with diameters up to 10 meters and weights of tens of tons. The working temperature can range from ultra-low temperatures of -269°C to ultra-high temperatures of 1430°C. Valves can be controlled in various ways, such as manually, electrically, pneumatically, or hydraulically. According to incomplete statistics, the variety of valve products in China has reached more than 4,000 types and nearly 40,000 specifications. Valves are widely used in urban water supply and drainage, heating, and gas supply systems, power generation systems of hydropower, thermal power, and nuclear power, as well as in the processing and transportation systems of petroleum, natural gas, coal, metallurgy, and mining, and in various industries such as ships, vehicles, aerospace, aircraft, and agricultural irrigation.
With the continuous development of modern industry and the progress of human society, the demand for valves continues to grow. A modern high-rise building requires a large number of valves, and a modern petrochemical installation requires tens of thousands of various valves. China, as the world’s factory, exports a large number of valve products to the world every year. Tianjin, as the base for butterfly valve products in China, holds a very important position.
