Stainless Steel 316 Needle Valve

Manufacturer, Supplier & Exporter of Stainless Steel 316 Needle Valve

Stainless Steel 316 Needle Valve is a precision control valve designed for regulating flow in small diameter piping systems. Manufactured using high-quality SS 316 material, it is known for its resistance to corrosion, high temperatures, and aggressive chemicals. These valves are widely used in applications where accurate flow control is required, such as instrumentation, gas sampling lines, hydraulic systems, and high-pressure applications..

Riddhi Siddhi Impex, a leading name in industrial valve manufacturing, is a trusted Stainless Steel 316 Needle Valve Domestic Supplier across India. With years of expertise and an advanced production setup, the company delivers precision-engineered needle valves that meet international standards such as ASTM, ASME, and DIN. Each valve undergoes rigorous quality testing to ensure flawless performance and longevity.

The SS 316 material, with the inclusion of molybdenum, enhances the valve’s resistance to pitting and crevice corrosion—making it ideal for marine and chloride-rich environments. These valves offer exceptional strength and durability, even in high-pressure conditions. The needle-shaped plunger inside the valve allows for precise adjustment of flow, which is especially critical in laboratory and analytical setups..

Riddhi Siddhi Impex manufactures SS 316 needle valves in a wide range of sizes (typically from 1/8” to 2”), pressure classes (up to 6000 PSI and more), and end connections including NPT, BSP, socket weld, butt weld, and compression fittings. This versatility allows these valves to be integrated into various systems, from process industries to aerospace and research facilities.

As a top-tier domestic supplier, the company has a strong distribution network in major Indian industrial hubs such as Mumbai, Delhi, Bengaluru, Hyderabad, Chennai, Kolkata, Pune, Ahmedabad, and Surat. The reach further expands to growing cities and special economic zones like Dahej, Ankleshwar, Valsad, Rajkot, Indore, Jaipur, Kanpur, Lucknow, and Coimbatore, ensuring timely delivery and support..
