-LCVI (Inline Check Valve); designed to prevent LNG vehicle cylinder pressure from LNG vaporization in liquid vaporizer. It is attached to the LNG vehicle cylinder.
-LEF (Excess Flow Valve); act as flow switches that automatically close when a flow spike occurs, preventing untrolled release of system fluid. It is attached to the LNG vehicle cylinder.
-LE (Economizer); designed to save the gas pressure in a liquid cryogenic cylinder that would otherwise be vented to the atmosphere through the pressure relief valve. It is attached to the LNG vehicle cylinder.
-LBM (Regulator); designed to buildup pressure on cryogenic liquid within cryogenic cylinder. It is attached to the LNG vehicle cylinder.
