A valve that automatically discharges gases and vapors to prevent a predetermined safe pressure from being exceeded. It is characterized by a rapid full opening action and is used for steam, gases, or vapor service. A relief valve, also known as a pressure relief valve, is a device that lowers the pressure to prevent damage to the system.

Their function is to protect pressure-sensitive equipment from damage caused by overpressure. They are critical in a pressure system to ensure that system failure are avoided. Incompressible fluid service is the inlet pressure at which a safety valve disk opens. For additional information regarding the product, please contact with dubuy support team.
