Based in Houston, USA, Paul Tube Fittings stands out as a top manufacturer and supplier of high-quality Stainless Steel 304 Ball Valves. The company is renowned for its commitment to excellence and engineering precision, delivering durable and cost-effective valve solutions for a variety of fluid control needs. These SS 304 ball valves are crafted to ensure reliable shut-off performance, resist corrosion, and simplify maintenance. With a solid foothold in sectors like water treatment, food processing, HVAC, and general engineering, Paul Tube Fittings guarantees that its valves adhere to strict quality and safety standards, making them a trusted option for both industrial and commercial applications.
Stainless Steel 304 Ball Valves are primarily composed of iron, featuring 18–20% chromium and 8–10.5% nickel, which provides outstanding general corrosion resistance along with solid mechanical properties. With a tensile strength of about 515 MPa (75,000 psi) and a yield strength of 205 MPa (30,000 psi), SS 304 performs well under moderate temperature and pressure conditions. It boasts good elongation and toughness, making it perfect for forming and welding tasks. While it may not resist chlorides as effectively as 316, SS 304 remains a cost-effective and durable choice for many non-aggressive fluid control systems.
