I.

Energy Sector
Oil and Gas: Used in oil field extraction, gas pipelines, and refineries to control the transportation of oil and gas. For example, gate valves and ball valves are used to shut off or regulate flow, preventing leaks and abnormal pressure.
Power Generation: Used in nuclear and thermal power plants to control the flow of steam and cooling water. Safety valves ensure equipment safety, and check valves prevent backflow of media.

Industrial Production
Chemical and Petrochemical: Used to control the transfer of acidic, alkaline, flammable, and explosive media, and to regulate the pressure and flow in reactors. For example, corrosion-resistant butterfly valves and diaphragm valves are applied in chemical pipelines.
Metallurgy and Manufacturing: Used in steel plants to control the supply of oxygen and coal gas. Control valves are used to regulate temperature and pressure in heat treatment processes.

Infrastructure and Construction
Water Supply and Drainage Systems: Gate valves and globe valves are used in municipal water supply pipelines to control water flow. Sluice valves are used in wastewater treatment plants to handle sewage, and check valves prevent backflow.
Heating and Air Conditioning: Balance valves are used in heating systems to regulate hot water flow, and electric control valves are used in air conditioning pipes to control refrigerant circulation.

Transportation
Marine and Offshore Engineering: Valves on ships control the flow of fuel, seawater, and compressed air. Deep-sea valves are used in subsea pipelines to enable remote control for oil and gas extraction.
Aerospace: High-precision valves are used in rocket fuel systems to control propellant ejection, and miniature valves are used for cabin environmental control in spacecraft to regulate gas flow.

Other Fields
Food and Pharmaceutical:Sanitary-grade valves (such as sterile butterfly valves) are used to control the transport of food and beverages, and pharmaceutical liquids, meeting clean production standards.
Environmental Engineering:Control valves are used in wastewater treatment plants to control the sewage treatment process, and valves are used in exhaust gas treatment systems to regulate gas purification paths.
Summary:Through their four major functions of “shutoff, regulation, safety, and control,” valves become the “pipeline nerve center” in sectors such as energy, industry, and infrastructure. Their performance directly impacts the safety and efficiency of the system.
