Active isolation of abrasive media

Whether it is silos, mills or extraction systems, our slide valves enable a safe isolation for dust or gas applications. The REDEX® slide valve is suitable for the isolation of fully developed explosions to the maximum explosion pressure.

The REDEX® Slide is available nominal pipe sizes from DN 50 to DN 150. Thanks to its practical design, the knife gate valve is suitable for all flow velocities and dust loads, it does not cause any pressure drop, and can be installed vertically, horizontally or at any angle.

Product specifications

  • Variably applicable
  • Extremely short closing times
  • Short installation distances thanks to a compact design
  • Flexible installation options at any angle
  • No loss of pressure
The system to be protected is equipped with pressure and/or infrared detectors. These can detect an explosion and send a signal to the knife gate valve. Depending on the size, one or more gas generators are activated, which close the slide valve due to the generated pressure. The closed slider blade effectively prevents the propagation of flames and pressure waves. Fast closing times also enable extremely short installation distances. During normal operation, the slide valves can be opened and closed pneumatically.
