Yodsak Tube Fittings, based in Bangkok, Thailand, stands out as a top manufacturer and supplier of precision-engineered stainless steel components tailored for fluid and instrumentation systems. One of their standout products is the Stainless Steel 321 Manifold Valve, designed specifically for high-temperature and corrosive settings. Renowned for its stability and durability under thermal stress, this valve is perfect for demanding industrial applications. Yodsak combines deep technical know-how, rigorous quality control, and cutting-edge manufacturing techniques to produce manifold valves that comply with international standards. They cater to industries such as petrochemical, oil and gas, power generation, and chemical processing, ensuring reliability and longevity in critical systems.
The Stainless Steel 321 Manifold Valve from Yodsak Tube Fittings is made from SS 321, a titanium-stabilized austenitic stainless steel known for its impressive resistance to intergranular corrosion and oxidation at high temperatures. It maintains strong mechanical properties, boasting a typical tensile strength of around 515 MPa and a yield strength of about 205 MPa. SS 321 is particularly well-suited for situations where there’s continuous or repeated heat exposure, handling temperatures up to 870°C. The manifold valve is precision-engineered for leak-tight sealing and can withstand pressures up to 6000 PSI, ensuring stable performance in high-stress environments, making it a reliable choice for thermal and corrosive applications.
