Similar to the aortic valve , the pulmonary valve opens in cardiac cycle ventricular systole , when the pressure in the right ventricle rises above the pressure in the pulmonary artery. At the end of ventricular systole, when the pressure in the right ventricle falls rapidly, the pressure in the pulmonary artery will close the pulmonary valve. The closure of the pulmonary valve contributes the P2 component of the second heart sound S2 . The right heart is a low pressure system, so the P2 component of the second heart sound is usually softer than the A2 component of the second heart sound.
