1. Universal action, means braking and remission time are not related to the brake cylinder size.Thus a distribution vale can be applied to brake cylinder in different size. 2. Braking speed: can reach 285m/s. 3. Sensitivity and stability, designed according to UIC standard. The distribution valve has the ability to respond synchronously to the slowly changing pressure of the brake pipe without accidental braking. 4. Overcharge control. 5. Maximum pressure limit, so as to prevent excessive braking force and wheel slip. 6. Non-exhaustive 7. It can be removed from the valve seat as a whole during maintenance. The valve seat establishes a connection with all the air lines of the vehicle, and all its parts do not need to be repaired.
