Engineered for Critical Marine Systems
Parker cryogenic valves are built for reliable performance in extreme LNG and fuel gas applications.
LNG Transportation
LNG carriers and bunkering vessels transport liquified gases across vast distances, exposing valves to cryogenic temperatures, mechanical stress, and continuous thermal cycling. Leak-free operation is critical to prevent LNG loss, ensure safety, and maximize efficiency.
Parker valves are engineered for durability, withstanding thermal expansion and contraction to prevent leakage and structural stress – ensuring uninterrupted, efficient transport of LNG.
LNG Storage & Processing
Onshore LNG storage terminals, floating storage regasification units (FSRUs), and gas processing plants face constant pressure fluctuations, temperature extremes, and boil-off gas (BOG) accumulation.
Parker valves provide long-term leak-prevention, maximize system efficiency, and withstand the demanding cryogenic environment, ensuring safe, low-maintenance operation.
Fuel Gas Supply Systems (FGSS)
LNG-powered vessels require precise, uninterrupted fuel delivery to maintain optimal engine performance and emissions compliance. Parker’s cryogenic FGSS valves handle both high and low pressures, prevent pressure buildup, and ensure the smooth, controlled flow of LNG, enhancing safety and operational efficiency.
Why is LNG Important?
- Lower Emissions: LNG produces fewer CO2, NOx, and SOx emissions compared to traditional marine fuels.
- High Energy Density: Offers more energy per unit volume than compressed natural gas (CNG).
- Safe Transport: LNG is non-toxic and non-corrosive, and any spill evaporates quickly without contaminating land or water.
* According to International Gas Union (IGU), the global LNG carrier fleet consisted of 701 active vessels as of the end of February 2024.
Built for Safety & Reliability
In marine and cryogenic applications, safety and performance are critical. Parker Bestobell valves are engineered to withstand extreme temperatures, pressure fluctuation, and harsh marine conditions, ensuring leak-tight performance, corrosion resistance, and minimal maintenance requirements.
DN150 - DN300
Float Level Isolation Valve (FLIV)
The Parker Bestobell FLIV valve is specifically designed to work in conjunction with Wärtsilä or Henri secondary float level measurement systems, providing secure isolation of the float from the cargo tank. It eliminates the issues commonly associated with gate valves, such as accidental cutting of the float tape, which can cause both the tape and float to fall back into the cargo tank.
DN15 - DN350
Globe Valves
Parker Bestobell stainless steel extended globe valves are engineered for maximum reliability in cryogenic marine applications, offering leak-free operation, extended service life and reduced maintenance costs for ship operators. Designed to meet Class compliance and fire safety standards, these valves ensure safe and efficient LNG flow control under extreme conditions.
The range includes:
- Miniature needle globe valves
- Screw-down non-return globe valves
- Manual globe valves
- Pneumatically actuated globe valves
- Hydraulically actuated globe valves
DN15 - DN150
Check Valves
Parker Bestobell cryogenic check valves are designed to prevent backflow and maintain system integrity in LNG and liquified gas pipelines. Available in swing check and lift check designs, these valves offer high flow efficiency, minimal pressure drop, and reliable sealing in extreme cryogenic environments.
DN15 - DN80, Class 1500-4500
High-Pressures Valves
Parker Bestobell high-pressure cryogenic valves offer exceptional durability, leak-free performance, and precise pressure control in high pressure applications. Designed for pressures ranging from class 1500 to class 4500, these valves are type-approved by all major Class societies and are machined from 316L stainless steel billet for superior strength and corrosion resistance.
The range includes:
- Manual globe valves
- Pneumatically and hydraulically actuated globe valves
- Pressure control valves
- Lift check valves
Certified & Type-Approved for Marine Use
