Home > Stainless Steel Needle Valves
Vinit Stainless, a renowned manufacturer and supplier in Chennai, India, presents high-precision Stainless Steel Needle Valves. They are designed to perfection for fine control of flow in critical applications where fine flow control of small flow rates is the key requirement. Our needle valves are carefully designed to provide consistent, leak-free performance and superior durability, even in harsh industrial conditions. We are dedicated to producing high-quality products that comply with high industry standards, offering integral components for instruments, control panels, and other fluid handling systems that need to be subjected to precise flow control.
Stainless Steel Needle Valves are typically made of grades such as 304/304L and 316/316L. Their content has high chromium to ensure excellent corrosion resistance, with nickel further increasing ductility and strength. Grade316/316L contains molybdenum, which greatly enhances pitting and crevice corrosion resistance, essential for aggressive media. Mechanically, they have high tensile strength (e.g., 515-620 MPa for 304/304L) and hardness, ensuring solid performance, accurate seating, and wear resistance, essential for accurate and reliable flow control.
