EFV Exces Flow Valve from SanOSub Italy #1053

the EFV drawing 

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

the installation of the EFV can prevent the sometimes fatal outcome of such incident. when the cylinder contents is suddenly released the EFV reduces the flow and thereby prevents that the cylinder is propelling around, a sample but nonetheless effective solution to protect life.

when valve is open quickly and unintentionally flow can be around 20,000L/m, when ex flow valve is installed flow at active mode reduce to 1000 L/M
