VENTEX® Valve
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.

Application
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.
Mechanism
Without air flow, the closing body is in the open position. In normal operation, the air flows around the open poppet within the valve body. In the event of an explosion, the pressure wave forces the sealing poppet closed against the closing-body gasket. The valve locks, effectively preventing the spread of flames and pressure waves.
