Spring loaded relief valve
Spring Loaded Relief Valve
A Spring Loaded Relief Valve is a crucial safety component designed to automatically release pressure from a system when it exceeds a pre-set limit, thereby protecting equipment, pipelines, and personnel from overpressure-related hazards. Operated by a precisely calibrated spring mechanism, the valve opens proportionally or fully once the system pressure surpasses the threshold, discharging excess fluid or gas and re-sealing once normal conditions are restored. These valves are widely used in industries such as oil & gas, chemical processing, power plants, and water systems to ensure operational safety and regulatory compliance. Their simple yet robust design makes them highly reliable for continuous service in high-pressure environments.
Built with durable materials such as stainless steel, carbon steel, or bronze, Spring Loaded Relief Valves offer resistance to corrosion, wear, and temperature extremes. The compact, self-contained design eliminates the need for external power or control systems, making installation and maintenance straightforward. They are ideal for protecting pressure vessels, pumps, compressors, and pipelines. These valves are customizable in terms of pressure range, discharge capacity, and end connections to meet specific system requirements. With fast response times, high accuracy, and consistent performance, Spring Loaded Relief Valves provide critical pressure control in both static and dynamic conditions.
