Product Catagory
These dust explosion-proof and explosion-venting products, possessing independent intellectual property rights, are based on thirty years of experience in explosion protection for aluminum powder equipment.From product mechanical design, explosion-proof performance, and explosion venting efficiency to sophisticated manufacturing processes, they are all designed to prevent the propagation of flames and pressure, providing comprehensive protection for the safe production of companies handling combustible dust.
Dust Explosion Isolation and Venting
Dust Explosion Protection Production Protection
Explosion isolation valves prevent the spread of flames; flameless explosion venting releases pressure and extinguishes flames (used for indoor explosion venting); explosion vents release pressure (used for outdoor explosion venting).
Explosion Isolation Excellence
Mechanically explosion-proof and electricity-free, our isolation systems feature a self-locking mechanism that enables instant response to pressure waves. The valves open fully to absorb shock and block secondary explosions effectively.
Certified Reliability & Customization
Each component is CE certified and type-tested for St1 and St2 dust applications. Manufactured to high standards, our products provide flexible installation options and long-term operational safety for dust-handling industries.
