Ventex Explosion Isolation Safety Valve

VENTEX® valves are often used when explosion-proof decoupling of pressurized containers is required, or air supply openings must be secured effectively against flame and pressure discharge. The decades-proven design offers you an effective, passive explosion safety solution. These valves can be controlled with or without external energy and offer simple and reliable explosion safety due to their extremely low response pressure and ease of maintenance.


VENTEX® can be used in plants that process combustible dusts (incl. metal dusts), gases or hybrid mixtures.

  • Animal Feed Production


Without air flow, the closing body is in an open position. In normal operation, the air flows around the open closing body. In the event of an explosion, the pressure wave presses the closing body against the closing-body gasket. The valve locks and thus prevents the propagation of flames and pressure waves.


  • Low response pressure.
  • Short mounting distance.
  • Used for Dust- and/or Gas explosion (Incl. metal dust & hybrid mixtures).
  • Passive closing principle.
  • Bi-directional isolation.
