A muscular valve is like a strong flap that is capable of opening and closing at will. An example of a muscular valve is the pyloric sphincter.
The vagus nerve controls the pyloric valve. It helps regulate the passage of food from the stomach to the small intestine by controlling the muscular movement of the pyloric valve.
There is no distinct valve at the junction of the pulmonary veins and the left atrium. Instead, the area where the pulmonary veins enter the left atrium is characterized by a muscular ridge, which can have a valve-like function by helping to prevent backflow of blood. However, this structure is not a true valve like those found in other parts of the heart.
the left atrioventricular valve is also called bicuspid valve as it consist of two muscular flab or leaflets that prevents the backward flow of blood from the left ventricle to the left atrium.
The esophagus connects the pharynx with the stomach. It serves as a muscular tube that carries food and liquids from the mouth to the stomach for digestion. The lower esophageal sphincter, a muscular valve at the end of the esophagus, prevents stomach contents from flowing back up into the esophagus.
The esophagus is connected to the stomach through a muscular valve called the lower esophageal sphincter. This valve opens to allow food to pass from the esophagus into the stomach and then closes to prevent stomach contents from flowing back up into the esophagus.
The pyloric valve, or pyloric sphincter, is a muscular valve located at the junction between the stomach and the small intestine. Its primary function is to regulate the passage of partially digested food (chyme) from the stomach into the duodenum, the first part of the small intestine. By opening and closing, the pyloric valve ensures that the chyme is released in a controlled manner, allowing for proper digestion and absorption of nutrients while preventing backflow into the stomach.

Two of them are the pyloric valve, which opens and closes to let the contents of the stomach enter the small intestine, and the sphincter valve which opens to let the contents of the sigmoid colon move to the "outside world". Actually, "sphincter" is the general word for any such muscular ringlike valve.
