Applications:

The CNLN / Arman DA08B2 Copper Cryogenic Safety Valve provides dependable overpressure relief for a variety of low-temperature, high-pressure scenarios:

Mobile Cryogenic Trailers & Containers
Protects small-volume liquid-gas delivery units (e.g., liquid nitrogen or oxygen trailers) against overpressure risks during transit, loading, or offloading.

Skid-Mounted Cryogenic Pump Packages
Integrates seamlessly with cryogenic pump skids and modular units to safeguard against pressure spikes during fluid transfer, circulation, and pump startup/shutdown cycles.

Compact Storage Tanks & Dewars
Ideal for bench-scale or pilot-plant vessels that store liquefied gases, where minimizing footprint and weight is critical without sacrificing safety performance.

Analytical & Laboratory Gas Systems
Provides reliable overpressure protection for small-bore piping loops supplying gases to analytical instruments, research laboratories, and cryopreservation setups.

Specialty Refrigeration & Cold-Chain Equipment

Ensures safe operation of compact refrigeration units, cold racks, and temperature-controlled containers used in pharmaceuticals, biotechnology, and food-grade cold-chain logistics.
