Killark control stations are designed to contain and extinguish explosions. The cast aluminum housing and bolts can withstand explosion pressures. The contact surface between top and bottom is wide to allow for combustion gases to cool down, pass through, and release pressure without igniting any explosive environment.
Factory sealed pushbutton, selector switch and pilot light stations are designed to prevent the igniting of external hazardous atmospheres by the enclosed arcing devices. Factory sealed devices eliminate the need for external sealing.
Use in hazardous locations in the presence of flammable gases or vapors, combustible dusts or easily ignitable fibers or flyings.
