Flam Arresters are designed to allow the flow gases, liquids, etc. and prevent flame transmission. Flame arresters are composed of
individual FLAMEFILTER (flame arrester disc). Several FLAMEFILTER plus spacers and an enclosing cage from the flame arrester.
The FLAMFILTER is made of wound corrugated metal strips. The principle of flame quenching in small gaps is applied in PROTEGO
end-of-line flame arresters and PROTEGO in-line-flame arresters.
Valve Closed vessels or tanks filled with liquids must have an opening through which the accumulated pressure can be released and
vacuum in the tank or vessel compensated. For the purpose PROTEGO Overpressure and Vacuum Relief Valves are provided with
weight-loaded or spring-loaded valve disc. In case of overpressure in the tank, the overpressure valve disc guided in the housing is lifted
and releases the volume flow into the atmosphere. When there is a vaccum in the tank, the overpressure of the atmoshere lifts the
vacuum disc and the tank is vented.
Tanks in tank farms and large vessels not only need to be equipped with flame arresters and valves, but they also require special
equipment. To fulfill our customers' requirements we produce tailored valves, systems and devices for special applications
