The innovative butterfly valves from RICO Sicherheitstechnik AG allow any decrease of airstreams and are able to close 100% gas tight. We offer you two versions with the highest safety standards: The round RAPIDO and the rectangle QUADRO. The versions are available in STANDARD (the gasket surface is smooth) or in PERFEKT (with a control groove in the gasket surface). They are designed to be very compact and light. Since many years both products have been installed within various airconditioning plants wolrdwide. Furthermore this year the new generation of our RAPIDO valve will join RICO’s product range. The new RAPIDO will set new standards in the butterfly valve market and has a slimer appearance paired with optimized technology for maximum safety.

Functional principle

The butterfly valve regulates the airstream within a ventilation system. In a fully open position the air floats the most through the valve, but if it is fully closed, then the valve is 100% gas tight. The plate of RAPIDO and QUADRO can be moved by hand or with a pneumatical or an electrical drive to the aimed position. The version PERFEKT allows to control the gas tightness anytime with a hand pump and a manometer. This is also possible when the valve is already installed. A control pressure will be built up within the control groove in the housing and the gasket from the plate makes sure that no pressure will be lost.

Field of application

The butterfly valves RAPIDO and QUADRO are installed where harmful substances are ubiquitous:

  • Pharmaceutical industry (for example isolators)
  • Nuclear plants
  • Military and civil applications
  • Chemical / petrochemical industry
  • Research laboratories
  • Hospitals
  • Etc.
