Explosion Isolation Flap Valves
Explosion flap valves: certified ATEX isolation against pressure waves and flames for total plant process safety.
Explosion isolation flap valves are heavy-duty safety devices specifically engineered to prevent the dangerous transmission of explosion effects (such as pressure waves and flames) to upstream plant areas. Backed by the know-how developed in close collaboration with partners and workshops holding over thirty years of experience in process safety and industrial dust treatment, these devices act as highly effective passive mechanical barriers. In the event of an explosion in downstream equipment (e.g., a dust collector), the pressure wave forces the internal flap plate to close and lock instantly. This crucial action protects upstream production lines, eliminates extended plant downtime costs, and secures operator safety.
Certified in compliance with EN 16447:2014 and EU ATEX Directive 2014/34/UE
Automatic mechanical plate locking triggered directly by the explosion pressure wave
Suitable for both internal and external installation in PULL configurations
Product Features
Design Features
- Certified Passive Safety: Fully tested under EN 16447 standards to block flame and pressure wave propagation.
- Heavy-Duty Build: Welded carbon steel body providing structural durability, finished in industrial RAL 3000 coating.
- Bespoke Stainless Steel Options: Available upon special request in high-grade stainless steel for harsh or sanitary environments.
- Streamlined Maintenance: Features an easy-access top inspection hatch for rapid internal cleaning and visual checks.
