CARZ back-pressure flap valve
Designed to prevent the effect of a pressure wave and flames caused by an explosion from returning along the pipework in which it is mounted
It is effective up to a maximum declared reduced explosion pressure within the protected enclosure (typically ATEX Zone 20 internally) and acts as an isolating valve during the explosion.
The CARZ Explosion Isolation flap prevents the devastating effects of a pressure wave and flame front, from a dust explosion downstream, from traveling back along the ductwork which it is fitted. The product is manufactured according to ATEX quality assurance standards for production.

In normal operating mode it is held open against gravity by the dust laden air stream flowing in the direction opposite to that of the explosion pressure wave.
- Prevents devastating effects of a dust explosion from spreading
- Prevents stray dust returning along the duct when dust collector is stopped
- Available with flange or QF collar for
connecting to different pipe systems
- Suitable for transporting explosive dust
