Modern dressing production, due to the widespread use of modern mechanical and electrical equipment and automatic control facilities, the production of a high degree of scientific and technical, so the technical management of the concentrator has great significance, can be summarized as follows: 1. do Good technical management is a requirement for large-scale social production and a necessary condition for ensuring the normal operation of mineral processing. 2. Doing a good job in technical management is an important guarantee for the concentrating plant to comprehensively improve its economic benefits. Relying on technological progress and comprehensively improving the economic benefits of mineral processing is a top priority for modern plant management. Therefore, rationally organize and manage all technical activities of the concentrator, establish a good technical work order, ensure safe production, improve the quality of selected products and labor productivity, reduce the consumption of materials, fuel and energy, reduce the cost of mineral processing, and increase Corporate profits, producing more mineral processing products at the least cost to meet the needs of the country and the people, this is the key to strengthening the management of mineral processing technology ; 3. Strengthening technical management is the need to achieve four modernizations, industry and science The modernization of technology, which includes the modernization of mineral processing, and the key to the modernization of mineral processing, is the modernization of mineral processing technology. Valves are found in virtually every industrial process, including water and sewage processing, mining, power generation, processing of oil, gas and petroleum, food manufacturing, chemical and plastic manufacturing and many other fields.

People in developed nations use valves in their daily lives, including plumbing valves, such as taps for tap water, gas control valves on cookers, small valves fitted to washing machines and dishwashers, safety devices fitted to hot water systems, and poppet valves in car engines.
In nature there are valves, for example one-way valves in veins controlling the blood circulation, and heart valves controlling the flow of blood in the chambers of the heart and maintaining the correct pumping action.
Valves may be operated manually, either by a handle, lever, pedal or wheel. Valves may also be automatic, driven by changes in pressure, temperature, or flow. These changes may act upon a diaphragm or a piston which in turn activates the valve, examples of this type of valve found commonly are safety valves fitted to hot water systems or boilers.
More complex control systems using valves requiring automatic control based on an external input (i.e., regulating flow through a pipe to a changing set point) require an actuator. An actuator will stroke the valve depending on its input and set-up, allowing the valve to be positioned accurately, and allowing control over a variety of requirements.
