Main control valve 723-40-72100 Suitable for Komatsu excavators
PC200-8MO and PC200-8
The 723-40-72100 main control valve features a multi-way integrated
design, a compact structure, and is suitable for high-load,
high-pressure hydraulic environments. The hydraulic control unit is
the core control component of the Komatsu PC series excavator's
hydraulic system. It receives high-pressure oil from the hydraulic
pump and, through internal multi-way valves and spool valves,
precisely distributes the oil flow to the boom, stick, bucket,
swing, and travel actuators. This ensures coordinated and smooth
control of all movements and is a crucial guarantee for system
stability.

Installation Instructions
Shut down and disconnect power, ensuring hydraulic system pressure
is released.
Clean surrounding oil before removing the old valve, ensuring the
interface is clean.
Installate the new valve into the valve seat according to the
original installation sequence, ensuring the fixing torque meets
equipment requirements.
Connect the hydraulic lines, confirming reliable sealing.
Start the hydraulic system and check if each action responds
normally and without leakage.
