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).
