Home > Stainless Steel Needle Valves
Harsh Metalloys, Mumbai, India, is a top-grade manufacturer and supplier of premium stainless steel needle valves for accurate flow control in multiple industrial systems. Our needle valves are designed to withstand rigors, corrosion, and leakage, making them suitable for high-temperature and high-pressure operations. These valves are produced according to international standards and find extensive application wherever accurate regulation of fluid or gas flow is required. Harsh Metalloys offers needle valves in various sizes, pressure ratings, and end connections to serve oil & gas, chemical, petrochemical, pharmaceutical, and instrumentation industries with dependable and durable solutions.
Stainless Steel Needle Valves supplied by Harsh Metalloys are typically manufactured from SS 304, 304L, 316, and 316L grades having chromium (18–20%), nickel (8–12%), and molybdenum (2–3% in 316 grades) for enhanced corrosion resistance. These valves have superior mechanical properties such as tensile strength of 485–620 MPa and superior pressure-handling capacity. Accuracy-machined spindle and seat provide great control of flow rates. Suitable for both liquid and gaseous applications, these valves will function under high temperatures and pressures without loss of sealing integrity and dimensions during their working life.
