Bestobell launches compact cryogenic valve
The compact FLIV, which is 150mm in diameter and just 600mm high, was developed to cater for the use of smaller diameter floats that are now being specified by shipyards for secondary level monitoring systems on LNG carriers.
Duncan Gaskin, sales director at Parker Bestobell Marine, said: “It is really exciting to be launching our new compact FLIV. Our original FLIV valve has helped us secure a large market share in supplying LNG Carriers and this latest version is set to meet demand going forward.”
The patented Parker Bestobell Marine FLIV is installed on top of the cargo tanks of LNG carriers and isolates the gauge and float from the cargo tank. These essential valves prevent potentially dangerous boil-off gas from the cargo tanks.
Parker Bestobell Marine’s original FLIV valve is available in 300mm and 200mm diameters. The first FLIV was supplied to an LNG carrier in 2007 and since then has been fitted to over 120 similar vessels.
It was originally designed to work in conjunction with the secondary float system supplied by Whessoe (now Wartsila Tank Systems) and has now been adapted to work with a similar system manufactured by Henri Systems.
FLIV was designed by Bestobell Valves back in the mid 2000’s to eliminate the problems associated with gate valves that were originally used to isolate the secondary float level gauge from the cargo tanks.
It has an integral inspection chamber from which the float can be serviced, thus eliminating the need for a separate fabricated component. An open/close indication and lock ensures that the crew members cannot close the valve when the float is still in the cargo tank.
