Introduction：
ZJ1 relay valve is generally used for locomotive brakes.
It is generally installed on a pipe seat or integrated air circuit board. During installation, the relay valve seat gasket is sealed between the relay valve and the pipe seat or integrated air circuit board to connect the main air duct, train pipe and equalizing air cylinder air circuit.
It can not only charge the total wind to the train tube, but also discharge the compressed air in the train tube to the atmosphere.
The pressure change of the train pipe is controlled by the pressure change of the equalizing air cylinder, and the pressure change of the equalizing air cylinder is the result of the operation of the automatic brake valve
