STIF & STUVEX
About us
French Producer of components for passive explosion protection and bulk handling systems.
Main products are compression coupling for pneumatic handling and explosion protection systems ( vent panels, flameless and non return valves). Recently, STIF has acquired the company STUVEX and expanded its product range with solutions focused on active explosion protection, aimed at preventing, detecting, and avoiding explosions (explosion suppression systems, grounding systems, etc.).

Compression couplings
Pneumatic conveying vacuum or pressure systems
Explosion Vent panels
VIGILEX explosion vent panels meet all the essential health and safety requirements for even an explosive atmosphere (Directive 94/9/CE) . In case of a fire, the explosion vents are designed to evacuate : the pressure, flames and dusts, thereby protecting people and the industrial equipment. A simple and efficient protection system : VIGILEX explosion vents are made to resist depressions, pneumatic unclogging cycles, and to be used on silos, hoppers, filters and cyclones. Conformity : CE Certification and Production Quality Assurance Notification.
VIGIFLAM - FLAMELESS DEVICES
To protect indoor machinery the Vigilex VQ guarantees flameless venting and dust protection. No burnt or unburnt dust passes off. Even high temperature is reduced to a minimum. During normal venting an explosion is freely discharged, allowing flames and dust to exit from the process vessel. When the process is located indoors, ducts are generally used to convey the explosion outside the building.
VIGIFLAP
The VigiFLAP is a non-return valve designed to prevent overpressure or flame caused by a downstream explosion (dust collectors, filters, cyclones...) to propagate in the piping system. The valve is held open by a lever arm. It can be used both at the entrance and at the exit of the filter. This allows to isolate the filter from an explosion or an overpressure. In case of explosion, the valve closes and remains locked preventing the progress of the flame. The unlocking of the flap is done manually
VIGIFLAM VI - FLAMELESS DEVICE
To protect indoor machinery, the flameless explosion venting device Vigiflam VI is designed in a rectangular shape and consists of three main parts: body, filter, and a new innovative vent panel. This panel is weakened in the middle, allowing it to rupture when excessive overpressure occurs in the enclosure intended to be protected. The purpose of Vigiflam VI is to neutralize the flame effects produced during an explosion. Vigiflam VI is specifically optimized for conveyors — bucket, belt, chain, and screw conveyors — due to its compact design and low weight.
FLASH EXPLOSION SUPPRESSION SYSTEM
Flash™ explosion suppression systems have been designed to detect and suppress dust explosions in an initial stage by injecting suppressant powder into the vessel. Flash™ explosion systems have been tested and ATEX certified, meet SIL 2 safety integrity levels and are compliant with EN14373:2005 and EN15089:2009 standards. Flash™ systems consist of 3 major parts: − Explosion detector for detection of static pressure, dynamic pressure or light intensity increases − Control unit directing the operation and communication between detector and suppression bottles − Suppression bottles for fast injection of the suppressant into the vessel
