Features

Benefits

Cryogenic Compatibility

316L stainless steel/Inconel® construction withstands -162°C (-260°F) LNG temperatures without brittleness.

Fail-Safe Emergency Release

Automated (hydraulic/pneumatic) or manual triggers for rapid separation (≤1 second) during tanker drift, fire, or overpressure—prevents loading arm damage.

Dual Block-and-Bleed Sealing

Metal-to-metal seats + PTFE backup seals ensure zero leakage post-separation, critical for containing volatile LNG.

Impact-Resistant Design

Reinforced body and coupling lugs withstand dynamic forces during release, maintaining structural integrity.

Interlock Compatibility

Integrates with loading arm control systems (PLC/SCADA) for synchronized shutdown, enhancing operational safety.
