Isolation with explosion safety valve.


VENTEX® – passive explosion decoupling with Swiss precision.

VENTEX® valves are often used when explosion-proof decoupling of pressurized containers is required or air supply openings have to be secured effectively against flame and pressure discharge. The decades-old 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. Common application areas include the pharmaceutical industry, chemical/petrochemical companies and research laboratories.
VENTEX mit Zubehör


  • Low response pressure.
  • Short mounting distance.
  • used for Dust- and/or Gasexplosion (Inkl. metaldust + hybrid mixtures).
  • passive closing principle.
  • bi-directional isolation.
When there is no flow of air, the closing device is in the open position. Air flows around the open closing device. The pressure wave pushes the closing device against a seal, locking the valve and effectively preventing the spread of flames and pressure.
