During handling it may happen that a filled cylinder falls down and all of sudden allows the cylinder content to discharge, either via an unintentional opening or a broken-off valve. The thrust of escaping gas can cause the pressurized cylinder to propel around and in worst case injure people.

The installation of the EFV can prevent the sometimes-fatal outcome of such incidents. When the cylinder contents are suddenly released, the EFV reduces the flow and thereby prevents that the cylinder is propelling around, a simple but nonetheless effective solution to protect life!
