The operation of safety relief valves is based on the principle of pressure differential. Each SRV is equipped with a spring-loaded mechanism that holds the valve closed at normal operating pressure. When the pressure inside the system exceeds the valve’s set point, the force exerted on the valve’s disc overcomes the spring tension, causing it to open. This allows the excess pressure to escape safely and returns the system to a stable operating condition. Once the pressure drops below the set point, the valve will automatically close, thus sealing the system.
