The pulmonary semilunar valve is located in the right ventricle at the opening to the pulmonary artery, which carries deoxygenated blood from the heart to the lungs where it will pick up oxygen. During systole, which is the active part of the heartbeat, the valve is forced open by increased pressure inside the ventricle and blood flows from the heart into the artery. During diastole the pressure inside the heart returns to its lower state, and the pressure inside the artery causes the valve to close again, thus preventing the blood from flowing back into the heart.
The pulmonary or pulmonic valve (a semilunar valve) controls blood flow from the right ventricle to the "pulmonary trunk" that branches into the two pulmonary arteries carrying blood to the lungs.

tricuspid valve
The two atrioventricular (AV) valves, which are between the atria and the ventricles, are the mitral valve and the tricuspid valve.The two semilunar (SL) valves, which are in the arteries leaving the heart, are the aortic valve and the pulmonary valve.
Yes. The pulmonary valve is a semilunar valve between the right ventricle and the pulmonary trunk.

Pulmonary semilunar valve (pulmonary valve)
There are two semilunar valves: 1. pulmonic valvewhich is located at the opening of the pulmonary artery; and 2. aortic valve which is located at the opening of the aorta.
The pulmonary valve (the right semilunar valve)

The pulmonary valve
Pulmonary valve stenosis cannot be prevented
It is the pulmonary valve. Sigmoid is only a synonyme for semilunar (includes pulmonary and aortic valves).
The valve located between the right ventricle and the pulmonary trunk is the pulmonary semilunar valve, also known as the pulmonic valve. This valve prevents the backflow of blood from the pulmonary trunk into the right ventricle during the heart's pumping cycle.
tricuspid valve
I guess you refer to the pulmonary valve stenosis which usually is due to the valve calcification when less blood supply will go from right ventricle of heart to the pulmonary circulation. The right ventricle will be hypertrophied because it's working harder then before.
