Introducing B-Flap I: Same but better

Explosion isolation is an essential part of explosion protection design that protects your industry from the devastating consequences of an explosion. Its primary purpose is to prevent the transmission of a pressure wave and to stop the flame front between interconnected technologies, thus preventing possible secondary explosions and minimizing damage to the technology.

The RSBP spol. s r.o. introduces a modified explosion isolation flap valve B-FLAP I with improved technical parameters.

The innovated explosion isolation flap valve B-FLAP I was certified according to the standards EN 16447 and EN 15089. Our flap valve was tested at one of the most modern accredited laboratories, emphasizing intended use in real industrial plants.


  • certified according to EN 16447 and EN 15089
