Dipti Metal Industries proudly stands as the largest global Cryogenic Valves Manufacturer, supplier, stockist, dealer, distributor, and exporter from our base in Mumbai, India. We are recognized as a top worldwide leader for high-quality flow control solutions specifically engineered for ultra-low temperature service. Our manufacturing capabilities, combined with our extensive global sourcing from trusted, certified partners, ensure that all products rigorously adhere to stringent international standards, primarily BS 6364 and MSS SP-134 (for cryogenic valve design and testing), in addition to general valve standards like ASME B16.34 and various API specifications (e.g., API 600, API 608, API 6D). Our commitment ensures compatibility, safety, and superior performance across diverse industrial applications globally, particularly those handling liquefied gases at extremely cold temperatures.
Cryogenic Valves are highly specialized valves meticulously designed to maintain reliable operation and tight shut-off in environments where temperatures can plummet to as low as -196°C (-320°F) for fluids like Liquefied Natural Gas (LNG), liquid nitrogen, liquid oxygen, liquid hydrogen, and helium. Their unique design incorporates features critical for these extreme conditions, most notably the extended bonnet. This elongated bonnet stem construction ensures that the stem packing operates at a sufficient distance from the super-cold fluid, allowing it to function at ambient temperatures, preventing freezing, and maintaining a leak-tight seal. Furthermore, internal cavities are engineered to safely relieve pressure buildup from trapped liquid that could expand significantly upon warming. Materials are carefully selected for exceptional ductility and impact strength at cryogenic temperatures to prevent brittle fracture. Our comprehensive range includes specialized versions of Cryogenic Gate Valves, Globe Valves, Ball Valves (floating and trunnion), Check Valves (swing, lift, and dual plate), and Butterfly Valves. These are available in a wide range of sizes (NPS 1/2″ – 48″), pressure classes (ASME Class 150 to Class 2500, and equivalent PN ratings), and diverse end connections (Flanged, Butt-Weld, Socket-Weld), compatible with specialized materials such as Austenitic Stainless Steels, Duplex/Super Duplex Steels, Nickel Alloys, and certain Bronze alloys. Our unwavering commitment to stringent quality control ensures that every cryogenic valve we supply meets precise dimensional, material, and performance specifications, providing robust and durable solutions for demanding ultra-low temperature flow control applications worldwide.

Cryogenic Valves are specialized valves designed to operate reliably at extremely low temperatures, typically below -150°C (-238°F). Their primary function is to safely control the flow of cryogenic fluids such as Liquefied Natural Gas (LNG), liquid nitrogen, liquid oxygen, liquid hydrogen, or helium, preventing leakage, ensuring tight shut-off, and maintaining structural integrity under severe thermal stress. They are critical for isolation, regulation, and safety in cryogenic processes and storage.
Key standards governing Cryogenic Valves include BS 6364 (Specification for valves for cryogenic service) and MSS SP-134 (Valves for Cryogenic Service), which define design, testing, and material requirements specifically for low-temperature applications. Additionally, general valve standards like ASME B16.34, API 600 (Gate), API 602 (Compact), API 603 (Corrosion-resistant), API 608 (Ball), API 609 (Butterfly), and API 6D (Pipeline) apply to the basic valve body design and pressure ratings, adapted for cryogenic conditions.
Cryogenic Valves are distinguished by several key features: Extended Bonnets are essential to keep the stem packing at a sufficient distance from the cold fluid, allowing it to function at ambient temperatures and prevent freezing. They typically use specialized packing materials (e.g., PTFE, Graphite) suitable for low temperatures, often with live-loading to maintain seal integrity. Internal cavities are designed to prevent dangerous pressure buildup from trapped liquid expanding into gas. Materials are carefully selected for high ductility and impact strength at cryogenic temperatures to prevent brittle fracture.
We offer a comprehensive range of Cryogenic Valves, including specialized versions of Gate Valves, Globe Valves, Ball Valves (floating and trunnion), Check Valves (swing, lift, dual plate), and Butterfly Valves. The most common materials for cryogenic service are Austenitic Stainless Steels (like ASTM A182 F304/F304L, F316/F316L, A351 CF8/CF8M) due to their excellent low-temperature impact properties. Other suitable materials include certain Duplex/Super Duplex Steels, Nickel Alloys (e.g., Monel, Inconel), and specialized Bronze or Aluminum Bronze alloys, all chosen for their ability to maintain strength and ductility at extreme cold temperatures.
