A band of muscles at the opening of the stomach called the Cardiac (due to its proximity to the heart) Sphincter.
The cardiac sphincter is located at the top of the stomach and controls the direction of food passing through the esophagus so that no food will re enter the esophagus. The Pyloric sphincter stops bile and digested food from entering the stomach, this valve is located at the bottom of the stomach.

Its called the atrioventricular valve or just AV valve

Pyloric Sphincter
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 open to the mouth and the stomach to allow food and liquids to pass. The trachea is open to the nose and mouth, leading to the lungs to facilitate breathing and air flow.
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 ring at the end of the esophagus is the lower esophageal sphincter.
The esophagus-stomach valve, also known as the lower esophageal sphincter, is a muscle that controls the flow of food and liquids from the esophagus into the stomach. Its main function is to prevent stomach contents from flowing back up into the esophagus, helping to prevent acid reflux and heartburn.
The cardiac sphincter is located at the top of the stomach and controls the direction of food passing through the esophagus so that no food will re enter the esophagus. The Pyloric sphincter stops bile and digested food from entering the stomach, this valve is located at the bottom of the stomach.

All mammals and reptiles have an esophagus. The esophagus extends from the end of the windpipe to the stomach and is part of the digestive system.
