I would have to say; depending if it's the left or right side. Left side it would be the aortic valve and the right side would be the pulmonary valve.
The bicuspid valve opens and the tricuspid valve closes.
It's a valve that opens or closes flow through a radiator
The bicuspid valve opens and the tricuspid valve closes.
tricuspid/ right atrioventricular valve.
The pyloric sphincter is a valve that opens and closes to allow chyme to leave the stomach and enter the duodenum. The cardiac sphincter is a valve that opens and closes to prevent stomach acid from going up the esophagus.
The Valve is the piece that actually moves in and out, or "opens and closes" - the part of the block that the valve rests on is called the valve seat.
The exhaust valve duration can be calculated by determining the total angle from when the valve opens to when it closes. It opens at 57 degrees before BDC and closes at 29 degrees after TDC. Since there are 180 degrees between BDC and TDC, the duration can be calculated as: 57 + 180 + 29 = 266 degrees. Therefore, the exhaust valve duration is 266 degrees.
The atrioventricular valve on the left side of the heart is the bicuspid or mitral valve. The AV valve on the right is the tricuspid.
The intake valve opens to allow the fresh charge of air and fuel into the combustion chamber then closes to seal the chamber during compression.
one has three cusps (tri) and the other has two (bi)
left atrioventricular valve and left mitral valve
The atrioventricular valves close during systole, when the heart pumps blood out to the various body regions. The tricuspid valve closes to prevent backflow from the right ventricle to the right atrium, and the mitral valve closes to prevent backflow from the left ventricle to the left atrium.
