Valves are mechanical devices used to regulate, direct, or control the flow of fluids or gases in a system. They come in a variety of forms, including ball, gate, globe, and check valves, and are available in materials such as brass, stainless steel, and cast iron. Valves are used in a wide range of industries, from water treatment and sewage systems to oil & gas, HVAC, and firefighting systems. The advantage of valves lies in their precision control over fluid flow, making them indispensable for maintaining the efficiency, safety, and functionality of complex piping systems. Valves also provide ease of maintenance and are designed to handle high-pressure environments.
