Yes, there are.
The chordate tendineae prevent the valves from inverting. Meaning that they will only allow the valves to close and then stop. Something like a door stop.
VAlves are fine it will not bent valves
No arteries have valves, only veins have valves to stop backflow.
No. Gate valves are designed to be either completely open or completely closed. Regulating flow is best done with a globe or plug valve, or certain kinds of ball valves. A gate valve left partially open will eventually wear down so that it can never be completely closed.
We need valves (thin, flap-like structures attached to the heart walls) so that it can stop the blood from flowing backwards.
have your valves adjusted adjust your valves
your semi lunar valves stop slop from entering your left aorta and your lunar valves stop crud from entering your right ventricle. this is the purpose of your valves. but this is different in dogs as your septum helps fight against testicular torsion.
Oil check valves are designed to stop the drain-back of oil. A replacement valve costs between $25 and $30 depending on where you buy it.
Because the heart is designed to pump forward and the vascular system has valves that stop blood from moving backwards.
The external housing (shell) of gate and globe valves are similar, but the globe valve is designed to serve as a regulating valve, meaning that it can adjust the flow by the percentage of the opening. However, the gate valve is not designed to regulate flow, but to stop the flow. A gate valve should always be either fully open or fully closed. The main difference is in the form of the inner elements and the form of the flow inside the valves. In addition, the gate valve may have a rising or non rising stem while the globe valve is typically a rising stem design. The direction of flow through a gate valve is not important. However a globe valve has a flow direction indicated on the outer shell (body) which indicates the direction of flow from beneath the seat. In a gate valve, the closure element is a plate or disk which travels parallel to the plane of the seat. The gate in a dam is a well known example. In a globe valve, the closure element is usually called a "poppet", and it travels perpendicular to the plane of the seat. There are specific advantages and disadvantages to each type depending on the application. The application for a globe valve is regulating flow. It is not well suited for full stop isolation. The gate valve is an isolation valve and not designed to regulate flow.
