In what other structures of the circulatory system are valves found?
You have the atrioventricular valves that are the valves separating each atrium from the ventricles. The right AV valve is the tricuspid valve, while the left AV valve is the bicuspid/mitral valve. There are also two valves that lead from the heart to the pulmonary and aortic arteries. These are the pulmonary and aortic valves. They are both semilunar valves because of their shape.
What type of valve is a solenoid valve?
Solenoid valves are electromechanically operated valves which are controlled by an electric current, mostly used in fluidics. There are different types of solenoid valves, one or two port valves.
What are the different types of electro pneumatics valve?

What is considered upper heart valves?

What structures in the heart prevent the back flow of blood?
The heart has two types of valves that keep the blood flowing in the correct direction. The valves between the atria and ventricles are called atrioventricular valves (also called cuspid valves), while those at the bases of the large vessels leaving the ventricles are called semilunar valves.
