Marine-Grade LPG Vessel Valve for Cryogenic Transport Ships with
Anti-Vibration Locknut
Product Description:
Designed for maritime LPG carriers and bunkering vessels, this
cryogenic LPG Vessel Valve operates reliably at -196°C to +50°C.
The vacuum-insulated body minimizes heat transfer, while the
tungsten-carbide-coated ball ensures smooth actuation in
high-vibration marine environments. Its patented anti-rotation
locknut prevents loosening during turbulent sea conditions,
maintaining consistent seal integrity. Featuring a fire-safe API
607 design with emergency gas containment chambers, the valve
complies with IMO IGF Code and DNV-GL standards. The extended
bonnet allows above-deck operation of below-deck valves, enhancing
crew safety during LNG/LPG transfer operations.
Bullet points:
Vacuum jacketing reduces boil-off gas by 70% vs standard valves
DNV-GL Type Approval for offshore cryogenic service
360° rotating flange for flexible pipeline alignment
Fire-tested for 30+ minutes at 760°C
Integrated pressure relief port for chamber equalization
Specific application scenario:
Secure transfer of liquefied gas between FSRU (Floating Storage
Regasification Units) and shuttle tankers.
