Brief introduction:

    The Hitachi excavator EX300 cartridge type hydraulic pulse valve function is to control the pressure in the oil system, is usually installed in the main oil line or shock absorber back pressure in order to reduce the impact of hydraulic shift and lock- unlock the excavator run to maintain steady state. Generally installed in the main oil damper back pressure, in the transmission automatically upshifts and downshifts instantly or lock in the lock-up clutch lock and release action began when the oil pressure dropped, in order to reduce the shift and lock to unlock the impact of the excavator to run a more reliable.

    The cartridge type hydraulic pulse valve characteristics:

    As the pulse valve has a low-power, supporting the use of smart devices. Diaphragm upper dielectric pressure of the valve cavity through the pressure relief hole, so that the diaphragm is formed under the pressure differential, in the the import medium pressure, hold the diaphragm, the main valve is opened. The armature moves in the opposite direction, cut off the pressure relief hole, the medium through the main valve balance hole into the diaphragm upper shut the main valve port.
