Virgin Engineers is a trusted stainless steel 317 manifold valve manufacturer and supplier in Mumbai, India. We provide solutions that excel when it matters most. We provide a range of manifold valves, featuring SS 317 and stainless steel 317L choices, available in 2-way, 3-way, and 5-way setups. Explore gauge valves, remote mount options, and block & bleed manifolds designed for demanding tasks that require leak-proof performance and reliable isolation.
We use high-grade 317 stainless steel and 317L stainless steel materials that comply with ASTM A182 F317/F317L and meet ASME B16.34 design standards. People recognize these valves for their outstanding resistance to corrosion, especially in environments rich in chlorides. No matter if you're handling harsh chemicals or extreme temperature flow systems, these valves ensure reliable performance. These can endure pressures reaching 6000 PSI and operate effectively within a temperature span of -54°C to 232°C. We offer standard sizes like ¼”, ½”, ¾”, and 1” with NPT, BSP, or flanged end connections. Do you require a custom size? We’re ready to build it.
Industries such as chemical manufacturing, power generation, paper and pulp, oil and gas, and marine applications rely heavily on our SS 317L valve manifolds. The lower carbon content in 317L improves its weldability and reduces the likelihood of carbide precipitation. Our valves come equipped with PTFE or graphite packing, anti-tamper handles, and optional needle, ball, or regulating stem tips—each designed to meet specific system needs. Every valve undergoes rigorous testing for performance and leakage prior to delivery, in strict compliance with API 598 and MSS-SP-99 standards. Full documentation, including EN 10204 3.1 test certificates and inspection reports, is provided for assurance and traceability.
We take packaging seriously to prevent transit damage. Each valve is carefully wrapped in moisture-resistant film and securely packed in sturdy wooden boxes to guarantee safe delivery across the globe. Our warehouse inventory enables swift shipping throughout India, the Middle East, Southeast Asia, and Europe. If you need a reliable supplier for SS 317 manifold valves or expert assistance in selecting the appropriate stainless steel 317L valve for your system, Virgin Engineers is ready to assist you.
