reliefventtiileistä

Reliefventtiilit, known in English as relief valves or safety valves, are automatic pressure-relieving devices that are designed to protect a pressurized system or vessel from exceeding its maximum allowable working pressure. They are crucial safety components in many industrial and domestic applications. When the pressure within a system reaches a predetermined set point, the relief valve opens, allowing a portion of the fluid or gas to escape. This discharge reduces the internal pressure back to a safe level. Once the pressure drops below the set point, the valve automatically closes, resealing the system.

The primary function of a relief valve is to prevent catastrophic failure due to overpressure. Overpressure can occur for various reasons, such as equipment malfunction, thermal expansion of fluids, or a blocked outlet. The valve acts as a fail-safe mechanism, ensuring that the system remains within its operational limits and protecting personnel and equipment from potential damage or explosion. Relief valves are manufactured in various designs and materials to suit different pressure ranges, fluid types, and operating conditions, including steam boilers, pipelines, and chemical processing equipment. They are an essential part of pressure safety management.
