MUB brake system is in accordance with the UIC standards ,and have TSI certificate,to ensure the vehicle with MUB braking system and other vehicles fitted UIC can be mixed operation.
System configuration
MUB brake system is mainly composed of distribution valve MUD, weighing valve, brake cylinder, brake shoe adjuster, auxiliary reservoir ,flow throttle , angle cock, coupling hose etc
Part sintroduction
Distributor valve MUD
FunctionsDistributor valve MUD is the key part of the air brake system, controlling brake system to generate inflation, braking, ease and the other functions.

Weighing Valve type RGC-1A
FunctionsWeighing valve type RGC-1A provides two kinds of pressure of controlling signals to the MUD distributing value. one is "empty",the other is "loaded ".
Technical parameters- Operating temperature:-40~70℃
- Maximum moving distance of connect :65mm
- Effective moving distance of connect :6mm
- The response time, the empty spaces to loaded position
- Quickly move the connect to the loaded position, to keep the 3S above, the output pressure reached 300kPa within 30s .
- Quickly move the push rod to the loaded position,keep the 3S above , the output pressure can not cause the conversion from empty to loaded position.
- Response time - loaded position to an empty space
- Quickly release the push rod to the empty spaces, to keep the 3S above, the output pressure drop to 50kPa within 90s .
- Quickly release the push rod to the empty space, to keep 3S above, the output pressure can not cause the conversion from loaded to empty .

Slack Adjust Type ZTI-600
FunctionsType ZT1-600 slack adjuster can automatically shorten and stretch due to worn-out or replacement of the brake shoe,in order to maintain a constant brake clearance and piston stroke in brake cylinder .
Technical parameters- Operating temperature:-40~70℃
High-quality carbon steel
Slack Adjust Type ZTI-600
- Name
brake cylinder
FunctionsType ZT1-600 slack adjuster can automatically shorten and stretch due to worn-out or replacement of the brake shoe,in order to maintain a constant brake clearance and piston stroke in brake cylinder .
Technical parameters- Operating temperature:-40~70℃
- Diameter of piston:12in 、14in、16in .
- Piston maximum stroke:220mm
- Push rod minimum recovery force:600±50N

- Name
Auxiliary Reservoir
FunctionsAuxiliary reservoir is used to store air pressure,which is used as air source bringing the air pressure into brake cylinder through distributing valve when brake works.
Technical parameters- Operating temperature:-40~70℃
- Volume:75l、100l、125l series.
High-quality carbon steel
Auxiliary Reservoir
- Name
Hose coupling
FunctionsThe angle cock is used to close the air brake device in the vehicle and empty the the compressed air in hose connector.divided into type L and type R, type L is used for installing on the left side of the coupler, the type R is used for mounted on the right side of the coupler
Technical parameters- Operating temperature:-40~70℃
- Drift diameter:≥ 25mm
- Exhaust port cross section:≈80mm2
- Working pressure:0~1MPa
- Hand torque:9~20Nm

- Name
Flow Throttle
FunctionsThe main function is to avoid the sharp reduction of air pressure in auxiliary reservoir (and sharp reduction of brake force),which caused by the crack or falling-down of the hose pipe.
Technical parameters- Operating temperature:-40~70℃
- Drift diameter:2mm
Cast iron
Flow Throttle
- Name
Guard Valvee
FunctionsGuard valve is also named emergency brake valve,which is installed on brake van.It has the function of braking under emergency to ensure the train running safety.when the danger of train has been observed during running,it is operated by the guard in brake van.
Technical parameters- Operating temperature:-40~70℃
- Standard pressure:500kpa,adapt 600kpa
- maximum working pressure :700kpa
