A flow control valve is an essential component used to regulate the rate, direction, and pressure of fluids such as liquids, gases, or steam in a piping or hydraulic system. By adjusting the opening of the valve, it controls the volume of fluid passing through, ensuring smooth operation, efficiency, and protection of equipment. These valves play a vital role in maintaining system balance, preventing overloads, and achieving accurate process control in industries like oil and gas, water treatment, power generation, and manufacturing. Depending on the application, flow control valves can be manually operated or automatically controlled to match system requirements. Their versatility, reliability, and precision make them indispensable for enhancing performance and ensuring safety in various industrial processes.
