PEX ball valves are a popular type of valve because of their durability and reliability. These valves are used in water supply systems, heating systems, and air-conditioning systems. They are designed to regulate the flow of liquid or gas and offer good flow control, as well as a tight shut-off capability. The valve has a movable ball inside, which is rotated to start or stop the flow of the fluid.

The body of the PEX ball stop valve comprises two separate halves. The material used for the body is crucial in determining the overall strength and durability of the valve. The two halves of the body are connected by a threaded joint or a welded joint. The material used to make the valve body is generally selected based on its corrosion resistance, strength, and compatibility with the fluid that passes through it.

The most common material used in PEX ball stop valve bodies is brass. Brass has high corrosion resistance, making it a viable option for applications that involve corrosive fluids. Furthermore, it is a strong and ductile material that can withstand high pressures and temperatures. Brass is the most affordable material for valve bodies compared to stainless steel or titanium.

Another material used in PEX ball valve bodies is stainless steel. Stainless steel has good strength and corrosion resistance, making it suitable for high-temperature applications. The strong austenitic structure of stainless steel provides good durability and resistance to cracking. However, stainless steel is expensive compared to brass, making it less commonly used in PEX ball valves.
