EFV : Excess Flow Valve
Chroma Gas Sdn BhdType: Sale
More Safety in the field of breathing protection
Description
Functional description:
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 content 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!
Characteristics at a glance:
• prevents recoil / repulsion
• also activates when valve is opened quickly and unintentionally
• tested and approved by our Notified Body – BAM (Federal Institute for Material Research and Testing) in Berlin
• suitable for working pressure 200 and 300 bar
• available with sinterfilter or dip tube
• flow at activated mode reduced to 950 to 1400 l/min. - depending on valve geometry and EFV execution
• suitable for all valves from: VTI, Dräger, Interspiro, MSA and Scott (all manufactured by VTI)
• not suitable for quick filling of emergency systems (rescue cushions)
Installation:
Torque EFV with 10 Nm using a torque wrench AF10
Note:
It is mandatory to carry out a visual inspection of the EFV latest after a 5 year service, e.g. during recertification of the cylinder. Replace the EFV in case you detect damages and / or contamination!
