A pressure rotary lock is a system of two rotary valves interconnected by a pressurization chamber. The pressure rotary locks enable pressure-less feeding or discharge of powders or liquids to or from positive-pressure or vacuum-pressure areas. If ATEX 95 certified, the pressure rotary locks can be operated in Ex-zones or as standalone explosion isolation systems.

ExKop explosion isolation system
While being a rather unusual solution, this explosion isolation system provides two unique features. First, the explosion isolation valve can be triggered to close by a decompression panel opening system (in the explosion venting system) or a dedicated IR sensor. Second, the explosion isolation valve can be reset for repeated use after an explosion.
Speed WEY HSI explosion isolation gate valves
The Speed WEY HSI explosion isolation gate valves are most robust, heavy-duty explosion isolation systems. The operating principle is similar to knife gate valves, but the trigger response and closing times are extremely short.
VENTEX ESI explosion isolation valves
The VENTEX explosion isolation valves are available in a wide variety of sizes and versions for passive explosion isolation. The valve is intended for installation in the ductwork of dust extraction / separating systems, positive or negative pressure handling systems, drying systems, or granulation systems. In most cases, the valves are resistant to the maximum explosion pressure.
ATEX-certified rotary valves
ATEX-certified rotary valves (also known as rotary dispensers) are applied as feeding dispensers for bulk products and airflow-reduction gates in dust extraction systems, central vacuum cleaning systems, pneumatic handling systems, and in similar applications. If certified for compliance with ATEX 95, the rotary valves are approved for use in Ex-zones and as standalone explosion isolation systems.
Extinguishing cylinders type HRD
Application: explosion protection of equipment units (including silos, filters, cyclones, mixers, drying plants, pelleting machines, etc.) in presence of flammables at explosive concentrations levels. The HRD cylinders provide explosion protection for processing equipment units, vessels, and ductwork which contain class ST1 to ST3 particulate matter, gases and/or hybrid mixtures in all industrial sectors.
SNR non-return damper
The SNR non-return damper is a simple and cost-effective solution for isolation of an explosion origin by closing the ductwork and preventing further propagation of explosion to the remainder of the protected installation.
VigiFLAP non-return damper
As the only explosion-proof non-return damper on the market, it can be placed on vertical pipes and on the clean side of filters, effectively isolating the explosion. This is possible thanks to the use of technology that keeps the damper open until the explosion spreads. In the event of an explosion, the valve closes and remains locked, preventing the spread of the explosion and flame. The damper must be unlocked manually. Additionally, the VigiFLAP has a certificate for metal dusts.
