RK non-return (check) valves

GESTRA's RK (wafer-type) non-return valves are for sandwiching between flanges. 

The valve has a spring to allow installation in any position. 

The valve self-centering body uses patented centering cams for RK 86/ RK 86A which make installation easier and faster – reducing costs.

Our RK non-return valves are ideal for liquids, gases, and vapor applications.


What are the features?

  • Safe operation in industrial plants
  • Compact design, short face-to-face dimensions for easier installation
  • Wide choice of materials to suit applications across many industrial fluids

Au démarrage de l’installation le purgeur est complètement ouvert. Les condensats froids et l’air sont évacués. Avec l’augmentation de la température les lames en acier Duo se dilatent et tirent la tuyère étagée dans le sens de la fermeture. Immédiatement en dessous de la température de saturation l’organe de fermeture est fermé. L’effect thermodynamique établie dans la chambre de la tuyère étagée produit une force agissant dans le sens de la fermeture. French DBL_810587 Download PDF
