  • RID Class-2, 3, 5, 6 and 8 products.


Efficiency in all conditions


  • Manual control (basic).
  • Complete internal DN 80 safety device.
  • Operating temperature: -50°C  +85°C.
  • Can be removed in 80 mm of ice (without de-icing screw, actuating force < 25 daN).
  • Penumatically seal from 0.03 to 3 MPa.
  • Test pressure 4.5 MPa.
  • Open/close control with built-in lock and return spring (no fastening on the wagon’s chassis).
  • Rapid emptying via custom hydraudynamic profile (from cast house).
  • Faster mounting on new wagon thanks to automatic positioning by design and mounting from the outside.
  • Filling possible in gas phase without unlocking the bilateral control thanks to standalone operation of the DIS as an option.
  • Admissible filling rate (with or without operating the valves): 18 m/s.
