The Fike Mechanical Explosion Isolation system typically comprises an EPC controller, explosion pressure detectors of
type UC2 and explosion isolation valves (EIV or FAV) eventually combined with chemically isolation containers
depending the nature of the explosion hazard. Explosion isolation system as a protection system, suitable for use on
process equipment containing dust atmospheres without external hazardous gas atmosphere areas.
The Fike Explosion Isolations Valves are designed to act upon the detection at the incipient stage of a combustion, and
mechanically isolate the combustion. The system suitable for dust –air mixtures with a deflagration index or
equivalent Kst less than 330 bar*m*s
-1
(DN50-DN250) or 200 bar*m*s
-1
(DN300-DN400) and maximum explosion
overpressure Pmax <12 barg.
The following valve sizes are covered: DN50, DN80, DN100, DN150, DN200, DN250, DN300, DN350, DN400
Minimum distances Xmin and Maximum distances Xmax of the valve in meters from protected vessel.
On detection of an incipient explosion, the CIE (control and indicating equipment) activates the explosion isolation
system and initiates alarm systems. Control and detection of the combustion may be done by one of the following
devices in combination with CIE type EPC.
The FAV is in compliance with: EN 1127-1, EN 13463-1:2009 & EN 15089:2009.
