Home > Stainless Steel Needle Valves
Harshita Stainless produces and distributes high-precision Stainless Steel Needle Valves in Delhi, India. Our valves are specifically designed for precise flow regulation in instrumentation and process systems. Utilized where precise fluid or gas regulation is needed, they are made of top-class stainless steel to provide consistent performance in tough conditions. Coming in different bore sizes, end connections, and pressure ranges, these needle valves find application in laboratory applications, chemical dosing systems, and pilot lines. Harshita Stainless provides accuracy to valves, leak-tight sealing, and robust construction for industrial customers in India.
Our SS 304, 316, and 316L make needle valves provide average tensile strength of 500–700 MPa and yield strength of 200–300 MPa. With chromium and nickel alloys and molybdenum in 316 to give extra corrosion resistance. With precision-ground stems and seats, usually PTFE or PCTFE sealed, with ratings up to 10,000 psi working pressure. Having excellent leak-tight sealing, wear resistance, and long service life in severe flow control uses.
