In case of an explosion not only the plants could be destroyed, also people and their environment are in danger. The resulting flames and shock waves should lead people to high caution, because the possible damage is not only of monetary nature.
RICO Sicherheitstechnik AG has the mission to prevent such desasters and therefore designed the REDEX® Slide. In comparison to our other explosion isolation valve RICO slide valve (RSV), the REDEX® Slide is made for lower pressure areas. Regarding the function both isolation valves are installed in pipes, where the product floats and where pressure drops and obstacles are not allowed. Furthermore there is a difference between the isolation valves in the housings. The housing of REDEX® Slide is made of aluminium and the RSV is produced completely of stainless steel.
The application is equipped with sensors for pressure and flames. Those sensors register an explosion and send a signal to the isolation valve. Depending on the size of the isolation valve the signal activates one or more gas generators, which close the isolation valve.
In the closed position the propagation of the flames and the shock waves are effectively denied. Fast closing times allow additionally short installation distances. The isolation valve can usually be open and closed pneumatically.
