What is a three-way ball valve ?
Three-, four- and five-way ball valves are called multi-port valves. The three-way ball valve is the most common multi-port ball valve. A three-way ball valve has three ports or openings that are connected to piping or tubing for gas or fluid flow (media) to pass through. These ports are usually described as one inlet and two outlet ports or one outlet and two inlet ports depending upon the flow direction through the valve.

How is a three-way ball valve different from a two-way ball valve?
Two-way ball valves are widely used as shut-off valves for gases or liquids (media) moving through closed tube or pipe systems. This is because of their simplicity and reliability. Two-way valves have two ports or openings where pipe or tubing is connected to the valve. The ball in two-way ball valves has a single straight hole through it where the liquid or gas (media) passes through the valve.
