Stop paying a premium for valve failures and 12-week lead times. Thriveon's ISO 9001 certified LN2 solenoid valves, built with 316L SS and PCTFE seals, deliver reliable flow control down to -196°C—backed by expert OEM support and fast global shipping.
Get Your Custom LN2 Valve Quote → Shipped in 7 DaysFor plant managers and procurement leaders in the US, every minute of unplanned downtime costs an average of $22,000. When your LN2 solenoid valve fails, it's not just a part replacement—it's a cascading failure of your entire cryogenic loop. Here are the core pain points we hear every day:
At Ningjin Thriveon Valve Co., Ltd., we've spent over a decade mastering the metallurgy and sealing technologies required for reliable cryogenic service. Our LN2 solenoid valves are designed from the ground up for liquid nitrogen, LNG, and liquid argon applications. We combine China's advanced supply chain efficiency with rigorous ISO 9001 quality management to deliver a valve that outperforms the market—without the premium price tag.
Extended bonnet lengths, PTFE/PCTFE seals, and 316L stainless steel bodies prevent ice buildup and thermal locking. Rated for 1,000,000+ cycles.
Eliminate the middleman. As a vertically integrated foundry, we control the entire supply chain—from raw material casting to final assembly—saving you 30-50% vs. US/European competitors.
Need a specific coil voltage (12V DC, 110V/60Hz AC), a special NAMUR mount, or custom NPT/BSP connections? Our engineers will configure it. We speak your specs.
Standard LN2 models ship within 7-10 days. Custom OEM configurations are typically ready in 15-20 days. We keep a buffer stock of raw 316L SS castings to accelerate production.
Every valve undergoes a 100% factory test: helium leak testing, seat leak testing (API 598), and cryogenic cycling validation. Full material traceability included.
All valves are certified for CE, RoHS, and ISO 9001. We can also supply valves compliant with ASME B16.34, ATEX, and PED for specific regional requirements.

Our LN2 solenoid valves are trusted in American chemical processing plants, semiconductor fabrication lines (wafer cooling), medical gas manifolds, LNG fueling stations, and aerospace testing facilities. If your flow control application requires phase-separation prevention and zero leakage at cryogenic temperatures, this is your valve.
A: A true LN2 solenoid valve requires an extended bonnet to prevent cold from reaching the coil, materials proven to withstand cryogenic temperatures (316L SS body, PTFE/PCTFE seals), and a pressure rating suitable for the liquid-to-gas expansion that occurs in cryogenic systems.
A: Direct-acting valves use the solenoid force to directly open/close the orifice, making them ideal for small orifices and vacuum applications. Pilot-operated valves use line pressure to assist the opening, suitable for larger flow rates (CV > 1.0) and higher pressures. We can supply both types depending on your flow requirements.
A: Yes, we regularly manufacture LN2 solenoid valves with NPT (National Pipe Thread) connections for the US market. We also offer BSP, Flanged, and SW (Socket Weld) ends. Our factory is skilled at adapting to ANSI/ASME standards.
A: Standard models ship within 7-10 days. For custom OEM configurations (specific voltages, special connectors, custom packaging), we typically ship within 15-20 days. Urgent orders can be expedited.
A: Our engineering team can help calculate the exact CV based on your inlet pressure, downstream pressure, specific gravity of your media (0.967 for LN2), and required flow rate. Contact us with your system parameters for a precise sizing recommendation.
A: We hold ISO 9001:2015 for our manufacturing facility. All valves sold to the US market are CE and RoHS compliant. We can also supply valves certified to ASME B16.34, ATEX, and PED upon request. Full material certification and test reports are provided with every shipment.
Don't let another batch fail or another day of downtime eat into your margins. We are currently offering priority scheduling for US buyers. Request a free sample or a detailed quote within the next 48 hours to guarantee fast-track production. No risk—our valves come with a 100% performance guarantee or your money back.

"We switched to Thriveon LN2 valves after our previous supplier couldn't keep up with demand. Not only are the valves built better (316L vs. their old brass), but Thriveon saved us 35% on our annual valve spend. The helium leak testing they provide gives us confidence in critical loops."
Sarah L., Senior Procurement Specialist
Semiconductor Supply Chain, Ohio, USA
"Responsiveness is everything in our industry. Thriveon delivered a batch of custom 24V DC LN2 valves in 18 days—half the time of our previous supplier. The engineering team understood our spec immediately. They are now our primary cryogenic valve vendor."
Dr. Chen, R&D Director
Aerospace Testing Facility, California, USA
"We needed a valve that could handle extreme thermal cycling without sealing degradation. Thriveon's PCTFE-sealed LN2 valve exceeded our test cycle requirements. The technical data package they provided was comprehensive and exactly what our QA team needed."
Jason has 15+ years of experience designing and sourcing high-reliability flow control solutions for the chemical, semiconductor, and energy sectors. He bridges the gap between advanced Chinese manufacturing and stringent US market requirements. At Thriveon, he leads technical client engagements and ensures every valve meets rigorous EEAT standards for safety and performance.
