Alloy 20 Needle & Gauge Valves

Alloy 20 Needle / Gauge Valves, Alloy 20 CB3 Needle and Gauge Valves, Alloy 20 Gauge Bleed Needle Valves Suppliers, Carpenter 20 Needle & Gauge Valves, Incoloy 20 Gauge Valves, Alloy 20 Industrial Needle & Gauge Valve Manufacturers in Mumbai, India.

Virgin Engineers is a trusted manufacturer and supplier of Alloy 20 needle and gauge valves in India, providing high-quality solutions that deliver long-lasting performance in highly corrosive environments. These valves are made using Alloy 20 (UNS N08020), a nickel-iron-chromium alloy that offers excellent resistance to sulfuric acid, nitric acid, phosphoric acid, and chloride-containing media. Often considered a superior alternative to stainless steel 316, Alloy 20 is known for its ability to withstand pitting, crevice corrosion, and stress corrosion cracking. This capability makes it a preferred choice across industries such as chemical processing, petrochemicals, pharmaceuticals, food and beverage, marine, and paper and pulp.

The Alloy 20 needle valves manufactured by Virgin Engineers are used for accurate regulation of fluid flow in instrumentation and control lines. On the other hand, the gauge valves are used to isolate pressure gauges, transmitters, and other instruments, ensuring safe and accurate readings without compromising the integrity of the system. Both valve types are designed to perform well under high pressure and elevated temperatures, even when exposed to corrosive liquids or gases.

Our Alloy 20 gauge valves are available in sizes ranging from ¼” to 1”, with pressure ratings up to 6000 PSI. These valves can be supplied with various end connections, including NPT, BSPT, BSPP, socket weld, flanged ends, and double ferrule compression fittings. To ensure reliable sealing and long-term operation, each valve is built with high-grade PTFE or graphite packing. We offer design options including integral bonnet, bar stock body, and forged body configurations to meet different application needs.

Each valve is manufactured in accordance with international standards such as ASME, ASTM, and ANSI. Quality assurance is central to our production process, and every unit undergoes pressure and leakage tests before dispatch. We also provide complete documentation, including EN 10204 3.1 Mill Test Certificates and third-party inspection reports, when required by the client.

Virgin Engineers continues to serve a wide customer base with its precision-engineered Alloy 20 needle and gauge valves, offering both durability and excellent corrosion resistance. With strong technical capabilities and a customer-first approach, we ensure prompt delivery, export-grade packaging, and full support for both standard and custom valve requirements worldwide.
