WORKING PRINCIPLE AND PERFORMANCE

 

MB50 pneumatic bus folding door mechanism is the pump assembly and solenoid valve assembly.when the piston rod extended, the bus door is closed; When the solenoid valve is commutated, the piston rob indented , the bus door is opened .

MB50 bus door mechanism has the door opening and closing speed control function, it also has the adjustable cushioning function for the door opening . So the speed of bus door opening and closing speed can achieve the desired state. And  with smooth progress, small impact .

 

And we also have electric bus folding door mechanism and bus folding door panel and glass , door rubber. also bus folding door lock (model 123)
