REDEX® Slide

Active isolation of abrasive material.

REDEX® Slide
Whether for silos, mills or extraction systems, our slide valves enable safe isolation, and are also available for demanding CIP, dust or gas applications. The REDEX® slide valve has been specifically developed for the isolation of pressure-relieved devices with a reduced explosion pressure.
The REDEX® Slide is available nominal pipe sizes from DN 50 to DN 150. Thanks to the practical design, knife gate valves are suitable for all flow velocities and dust loads, they do not cause any pressure drop, and can be installed vertically, horizontally or at any angle.

reactivation kit

  • Wide application range
  • Extremely fast closing times.
  • Short installation distances thanks to a compact design.
  • Flexible installation options at any angle.
  • No pressure drop.
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 within milliseconds. 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.
