Pyloric valve
The valve preventing the movement of chyme from the duodenum into the stomach is called the pyloric valve. The pyloric valve consists of a ring of smooth muscle and is connected to the duodenum.
Pyloric sphincter controls the movement of food from stomach to duodenum. With parasympathetic or vagal stimulation it opens up or relaxes and with sympathetic stimulation it contracts or closes.

Pyloric Vavle
The Pylorus (the valve between the stomach and duodenum is the pyloric valve)
It serves to regulate the movement of food out of the stomach and prevents bile in the small intestine from moving back into the stomach.
stomach and duodenum
The duodenum is the valve between the stomach and the small intestine.
The pyloric sphincter, or valve, is a strong ring of smooth muscle at the end of the pyloric canal and lets food pass from the stomach to the duodenum. It receives sympathetic innervation from celiac ganglion. http://en.wikipedia.org/wiki/Pylorus
The stomach and first part of the small intestine (duodenum) is connected by pylorus which has 2 parts. The on the stomach opening is called pyloric antrum and the opening in the duodenum is the pyloric canal type.
A band of muscles at the opening of the stomach called the Cardiac (due to its proximity to the heart) Sphincter.
The Pyloric Sphincter controls the movement of food between the stomach and the small intestine.
