Systole: Period of ejection. AV valves closed Semilunar valves opened AV valves closed Semilunar valves closed Diastole: Period of isovolumic relaxation. Blood flowing back toward the relaxed ventricles causes the semilunar valves to close, which is the beginning of ventricular diastole.
Spring-loaded pressure safety valves use a compressed spring to hold the valve closed. The valve will remain closed until the process pressure exceeds the set point of the spring pressure. The valve will open 100% when the set point is reached and will remain open until a certain blow down factor is reached. Oftentimes the blow down is a percentage of the set point, such as 20% of the set point.
