The tricuspid valve is between the right atrium and right ventricle. Also,The valve which is under the most pressure to block blacflow of blood during ventricular systole is the mitral valve. Mitral valve is the one which is located between the left atrium and left ventricle.
The heart works with two processes: diastole and systole. Systole occurs when the heart contract himself to expulse blood to the vessels, and when the heart relaxes while it fulfills of blood is called diastole. During the systole process the tricuspid valve needs to be closed to allow the increase of pressures inside the heart cameras and then allow the expulse of blood. But, during diastole, tricuspid valve needs to be open to allow the correct filling of right side of the heart.
