RICO Sicherheitstechnik, the company based in Herisau, Switzerland, is launching the next generation of the proven Ventex explosion protection valve and offering customers a wide range of innovations and optimizations in the field of explosion isolation. The valve now features a flow velocity of at least 30 m/s in all nominal sizes, thus ensuring an even higher level of process reliability and flexibility. The valve can be placed directly upstream or downstream of pipe bends in the pipeline; double pipe bends or combinations of pipe bends in different directions are also no problem.
“In this way, we ensure significant advantages in plant design, as customers do not have to reserve as much space and a straight pipe section is not a requirement. The installation distance in the area of organic dusts has been extended and is between 2 m and 15 m, depending on the nominal size. These two innovations result in increased flexibility in the use of the passive explosion protection valve. Even in existing plants, integration is fast and easy,” says Lorena Rigor, Head of Product Management and Customer Service at RICO.
For processes involving metallic dusts, the new Ventex is also certified in nominal size DN400. Moreover, the new generation also achieves up to 20% better values in terms of pressure drop. In addition, RICO has responded to customer suggestions: the DN250 nominal size, which previously was not offered yet, has been added to the Ventex portfolio and is now available as standard. “We were also able to further improve the maintenance modalities as part of our research and development, as well as achieve important flow and gasket optimizations,” explains Lorena Rigor, emphasizing the need for gaskets.
