Excess Flow Valve (EFV)

02-Nov-2012

2nd Nov 2012 : In the interest of safety and inline with global best practices, Tekno Valves has developed Excess Flow device, for cylinder valves to be used for breathable cylinders. The Excess flow device is designed to significantly reduce flow of the valve (but just enough to allow the fire fighter to breathe) in case of sudden increase in flow possibly due to inadvertent and sudden opening of the valve or shearing of the valve inlet. The EFV has been successfully tested by BAM Berlin (BAM procedure DGA-12-012) to functional requirements with the intended application. The use of EFV (see video link) reduces the effect of the resultant thrust due to sudden increase in flow from the valve inlet, eliminating cylinder tipping over or being dangerously propelled.
