Home > Stainless Steel Needle Valves
Nakamura Stainless is a well-known manufacturer and supplier located in Pulau Ujong, Singapore. It provides precision-engineered stainless steel components for demanding applications. Among its products, Stainless Steel Needle Valves are notable for their accuracy in flow control. These valves are designed for systems that need fine regulation of fluid or gas flow. They deliver leak-proof performance even under high pressure. Nakamura Stainless makes sure each valve goes through strict quality checks, making them ideal for industries such as oil and gas, chemical processing, instrumentation, and laboratory systems where precision and durability are crucial.
Stainless Steel Needle Valves are usually made from SS 304 or SS 316. They contain 18–20% chromium and 8–14% nickel, with the 316 grade also having 2–3% molybdenum for better resistance to corrosion and pitting. These valves are strong, with tensile strength ranging from 515 to 620 MPa and excellent pressure-handling ability. Their design features a finely threaded stem and a tapered, needle-like plunger that allows for gradual and precise flow adjustment. The stainless steel body offers resistance to high temperatures, chemical exposure, and wear, making them suitable for critical and high-purity applications.
