It’s very important to choose correctly ball valve between brass ball valve and stainless steel ball valve for your project. Which is better between brass and stainless steel? We only can indicate which one better suitable to your project. Let us make clearly a comparison as bellow.
Material. The main material about brass ball valve is brass. The brass usually contains mostly copper and zinc with a small percentage lead. The main material of stainless steel ball valve is stainless steel. The stainless steel usually contains iron, chromium and nickel. So, their different composition between brass ball valve and stainless steel ball valve decide their different working environment and how to choose them.


Corrosion resistant. The stainless steel contains chromium-nickel alloy which make it becomes highly resistant to corrosion. Although, the brass also have resistant to corrosion, but its capacity of corrosion resistant is lower than stainless steel.
Mechanical property. Copper and zinc, which are soft and brittle metal. Together, they form brass, a strong and malleable alloy. It’s easily machined and welding when produce the brass valve. Stainless steel is a very durable and resilient metal. So stainless steel ball valve is able to effectively resist leaks. Stainless steel valve is also able to work in more temperature than brass and tends to last longer. Stainless steel ball valve is best options for high pressure and temperature situations. Stainless steel valve used in more wide range of field.
Price. Stainless steel valve is more expensive than brass valve. If both two material valves meet needs of same project. We have to choose the brass valve to save money.
FDA approvals. Because of the brass contains s small percentage lead, the FDA does not approval unless they are certified leed-free.
Consider these above factors and decide which material suitable is when you start to your next project.
