A safety valve is a pressure protection device designed to automatically release excess pressure when it exceeds a preset limit. It helps protect pipelines, tanks, boilers, pressure vessels, and other equipment from potential damage caused by overpressure. Safety valves are manufactured with durable materials and can be configured for different pressure ranges, connection sizes, and operating conditions. They are widely used in industrial processing, steam systems, oil and gas, chemical plants, water systems, and other applications where reliable pressure protection is required.
