French safety specialist SERV Trayvou Inter-verrouillage has developed a new version of the RGV, its lockable Guillemin-type hose coupling, to prevent tanker drivers delivering their load to the wrong silo. Now more resilient and easier to use, the latest RGV enables the safe transfer of solids and liquids via trapped-key interlocking technology.rnThe product is simple to operate. The operations manager gives the driver an individually-coded key, which will only permit the driver to connect the tanker s hose to a specific silo. The driver inserts the key into the lock on the RGV and turns it, unlocking the RGV and allowing the hose to be attached to the coupling.
