The most widely used explosion isolation in the world.
As a passive explosion isolation valve with many years of proven operational safety, the VENTEX® has been acting as an effective and reliable pressure and flame arrester for over 50 years – completely without external energy, control and detection. With numerous configuration and application options, the VENTEX® adapts to your individual needs.
We guarantee safety.
We put all our approved products through their paces. In over 1,500 explosions, our components have all proven themselves in explosion protection.
Explosion isolation valve VENTEX®. The benchmark.
Protects and has proven itself for decades in a wide range of systems and various applications and guarantees maximum safety without external energy.
Low pressure drop thanks to aerodynamically optimised design. Minimal maintenance required, can be used vertically or horizontally.
Maximum 30 m/s flow velocity in explosion direction for flexible systems Design with pipe bends in front of the valve, versus flow separation through pipe bends.
Sealing materials for various requirements regarding temperature, process and media resistance. Approved for organic and metallic dusts and hybrid mixtures.
Connection flange according to EN 1092-1 or ASME B 16.5 Class 150
Easy release from the outside. Configurable as single-acting, double-acting or non-return valve depending on the process.
Passive protection system, no detection and control necessary.
The passive explosion isolation
As the most widely used isolation component in the world, VENTEX® is used in a variety of areas, such as the pharmaceutical, chemical or food industries, metal processing and a multitude of other industries.
VENTEX® in rest position
In the resting state without air flow, the closing body is in the open position.
VENTEX® in normal operation
In normal operation, the medium flows around the open closing body.
VENTEX® after explosion
In the event of an explosion, the pressure wave presses the closing body against the closing body gasket, the valve is locked and thus the spread of flames and pressure waves is prevented.
«Our top priority is to supply plants and systems that take into account the protection of human life, the environment and the operator’s property. »
Henning Wolf, Glatt-Gruppe
