Isolation Ventex Valves
Rico Ventex New Generation Explosion Isolation Valve
The Rico – VENTEX New Generation (New Gen) Explosion Barrier/Explosion Isolation Valve is a ground-breaking passive explosion protection system that ensures superior process reliability and flexibility. Certified for organic and metallic dust explosions, this innovative valve is designed with enhanced flow velocities, ensuring robust prevention against explosion propagation.
Specifications
- Supports a flow velocity now up to 30 m/s, maximum air-flow in the same direction as the explosion.
- The valve can be placed directly upstream or downstream of pipe bends in the pipeline, offering significant advantages in plant design.
- Equipped with full integrated mechanics, the locking and switch actuation are integrated into the “star” assembly.
- Can withstand temperatures up to 300°C, catering to higher temperature environments.
- Fitted with a valve poppet gasket recessed into a pocket in the housing and locked into place, guarantees reliability.
- Certified for Metallic dust explosions to sizes up to DN400
Common Applications
- Offers explosion isolation within various application areas such as silos, mills, drying chambers, separators, dust collectors, extraction systems etc.
- Tailored for industries such as Food, Pharmaceuticals, Chemicals/Petrochemicals, Research laboratories, Wood, among others handling combustible dust.
- It offers extended installation distance in the area of organic dust between 2 m and 15 m.
- The valve is easy to integrate into existing plants and ensures maintenance is cost-effective, simple, and fast, promising a rapid recommissioning process.

Rico Ventex Type 6 Explosion Isolation Valve
The VENTEX® ESI Type 6 is an explosion isolation valve designed to stop explosion propagation through pipelines. The explosion pressure surge in a pipeline is sensed by explosion pressure and with this highly sophisticated safety device, the piping system is immediately closed off, thus preventing the flame and the pressure wave from spreading into other areas of the installation. The VENTEX® ESI Type 6 is approved for use in potentially explosive atmospheres of different types.
Specifications
- Available in both mild steel and stainless steel to match various industrial demands.
- Versatile orientation with horizontal, vertical, single acting, and double acting options.
- Including VENTEX ESI-E for explosions from top and bottom, and VENTEX ESI-D with a double-acting check valve feature.
- Supports a flow velocity up to25 m/s, maximum air-flow in the same direction as the explosion.
- Up to 35 m/s in the direction opposite the explosion helps maintain operation with high volumetric flow rates.
- Range from DN100 to DN600 accommodating a broad spectrum of pipe sizes.
- Capable of handling minimum and maximum explosion pressures tailored to the material type, from organic dust to hybrid mixtures and metallic dust.
Common Applications
- Ideal for any industrial setup where combustible materials are transported through process piping systems such as ducting, requiring explosion isolation valves for safety compliance.
- Used extensively in dust collection systems where explosive dust particles pose a significant hazard.
- Essential in chemical processing plants where the mix of chemicals and processing methods can lead to explosive atmospheres.
- Commonly installed in the agriculture industry, particularly in locations of grain processing facilities where grain dust is prevalent, such as milling operations.
- Applicable in settings where metallic dust, such as aluminum, is present and may carry the risk of combustion in metal processing plants.
