Explosion Isolation Flap Valve CARZ-N Ø315-1000mm

Explosion Isolation Flap Valve CARZ-N - protective system

Explosion Isolation Flap Valve type CARZ-N prevents a transmission of explosion pressure wave and flames front from the filter to your workplace. By using our CARZ-N Explosion Isolation Flap Valve, you reduce the risk from dust explosion for both people and equipment.

Function

During normal operation, the valve is kept open, and large opening angle ensure low pressure drop. In case of an explosion in the filter, the pressure wave will force to close the flap plate and lock in position. When flap plate is closed it makes an effective barrier against approaching flame front. This prevent the explosion from being transmitted from the filter to upstream work areas.

No matter what industry you are in or what type of dust is generated in your factory, we can provide the complete dust explosion protection solution of filters, and explosion isolation flap valves.

Independently tested to latest and most stringent standards and regulations
Compliant with international dust explosion protection codes (ATEX, NFPA69, IECEx)
Widest range of sizes, applications and filter system configurations on the market (e.g. approval for positive and negative pressure systems, approval for St2 dusts up to size 630 inclusive)
Manufactured fully by Nederman under certified quality assurance system, ensuring highest level of quality and reliability
