The material that a ball valve body is made of is important for determining its function. Stainless steels and brasses are common options because they offer good corrosion resistance and strength at high temperatures. They can also be shaped into specific shapes through a process called forging.
Seals and Bodies
The materials that seal the balls in a ball valve are another important consideration for ensuring optimal performance. Depending on the fluid media that will pass through them, these can be made of brass, stainless steel, or PVC.
Lead Free Brass
If a valve is being used for potable water, it is important to choose a valve that is free from lead. This is because lead can cause serious health issues in those who drink it.
Stainless Steel
Stainless steel is a type of iron-carbon alloy that contains at least 10.5% chromium by weight. Chromium makes the steel stronger and more resistant to corrosion. It is available in a variety of compositions, but the most commonly used are 304 and 316. Stainless steel is also easy to weld and can be forged into specific shapes.
