ductus arteriosus
There are not valves in the pulmonary artery or the aorta. However there are valves between these and the heart. Between the right ventricle and the pulmonary artery there is a valve referred to as the pulmonary semilunar valve. Between the left ventricle and the aorta there is a valve called the aortic semilunar valve.
The blood vessels that take oxygenated blood from the right ventricle to the lungs are the pulmonary artery. It is part of the pulmonary circulation.
The valve between the heart and the aorta is the aortic valve, and the valve between the heart and the pulmonary artery is the pulmonic valve.
An artery is the vessel that carries blood away from the heart. The pulmonary artery carries only deoxygenated blood after birth.
The pulmonary semilunar valve, also called the pulmonic valve, prevents blood that was ejected out of the right ventricle into the pulmonary artery from flowing back into the right ventricle.

Pulmonary
This is called a shunt. One that occur between the Pulmonary artery and the Pulmonary vein, would be a left to right shunt. So what would happen? The blood from the Pulmonary vein (having the high pressure) would enter the Pulmonary artery. The results would be that the blood just goes back to the lung for another cycle with be deoxygenated.
The artery that sends blood from the heart to the lungs is called the pulmonary artery. The pulmonary vein delivers blood back to the heart.
the pulmonary artery and pulmonary vein
Artery - always carries blood FROM the heart Vein - always carries blood TO the heart The vein which brings blood to the heart from the lungs is the PULMONARY VEIN ('pulmonary' = lungs). The one carrying blood away from the heart to the lungs is the pulmonary artery. Easy.
All arteries (the red blood vessels) carry oxygenated blood. it's the viens (the blue blood vessels) that don't carry oxygenated blood. However the Pulmonary artery carries Deoxygenated blood to the lungs to be reoxygenated, as it carries blood away from the heart it is called a Artery.
If you are referring to the valve that separates the left atrium from the left ventricle, it is called the mitral valve.
