Available as an option on all VTI valves:
During handling it may happen that a filled cylinder falls down and all of a sudden allows the complete cylinder contents 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 is 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!
