Direct relief valve is a key device used to control the pressure of liquid systems. Its main purpose is to maintain the system within the designed working pressure range and prevent damage to pipelines, equipment, or systems due to excessive pressure. This type of relief valve sets a set pressure threshold in the system. Once the system pressure exceeds the set value, the valve will open and release excess liquid, maintaining the pressure at a safe level. This working principle effectively prevents the danger caused by overload in the system, ensuring its reliability and stability. Direct relief valves are widely used in various industrial, chemical, energy and other fields, providing important pressure control and protection mechanisms for various liquid systems.
