MUB air brake system was developed according to UIC standard, and the technical parameters and interface sizes can meet the requirements of UIC standard, which makes sure that the vehicles mounting MUB air brake system can operate with the vehicles mounting other UIC standard brake system (eg. the vehicles installing Knorr or Wabtec brake system).
The MUB brake system is fully compliant with UIC standards and got the TSI certificate in 2013 and is on the ERA (Eu Railways) database.
MUB brake system include: distributor valve, sensor valve, brake cylinder, auxiliary reservoir, bidirectional slack adjuster, throttle , angle cock, hose coupling, etc.
MUB brake system has been used in Pakistan, Sudan, Myanmar and Gabon since 2009 with stable and good performance.
Pictures of MUB brake system are shown below:
Pakistan box wagons in 2009
Sudan box wagon in 2014
Myanmar box car in 2016
Gabon open-top wagon in 2018
The parameters of MUB air brake system are designed based on UIC standard, and IRIS Quality Management System is strictly followed during our R & D process, so as to ensure the performance and the reliability of the products.
