Isolation with explosion safety valve VENTEX®
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.
Applications
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
Example using the VENTEX® ESI-E/D: Explosion safety with one-way or two-way acting system without external energy.
Idle state
When there is no flow of air, the closing device is in the open position.
Normal operation
Air flows around the open closing device.
Explosion event
The pressure wave pushes the closing device against a seal, locking the valve and effectively preventing the spread of flames and pressure.
Your advantages
- Low response pressure
- Short mounting distance
