Brass valves are made from copper and zinc alloys, offering malleability, corrosion resistance, and increased durability. As brass valves are stronger and harder than copper, yet more malleable than steel and iron, they are more resistant to cracking. They are resistant to corrosion and can withstand extremely high temperatures.
In a 3-Way Valve with an L-shaped hole, there are two different outlets.
It is possible to allow two inlets to flow into one outlet by using three-way valves with T-shaped holes.
