What is the difference between standard and refillable gas cylinder? As you can see on the video below refillable LPG bottle is equipped with a special overfill protection valve which prevents to overfill the bottle with propane. Safe level is 80% and it is not to possible to control on standard bottle without a weight during refill process. With refillable gas cylinder you do not need to worry about overfill as the valve stops LPG filling when the bottle is 80% full. Both standard and refillable bottles are normally equipped with safety relief valves set up to open at 27bar pressure.
