DH220-5 / DH225-7
Because hydraulic system specifications may vary according to machine serial number, production year and equipment configuration, please confirm the original valve information before ordering.
Main Function
The excavator main control valve is one of the central components of the hydraulic system. It receives pressurized hydraulic oil from the hydraulic pump and directs the oil to the appropriate actuators according to operator commands.
In compatible applications, the valve helps control hydraulic functions associated with:
Boom · Arm · Bucket · Swing · Travel · Auxiliary Hydraulic Circuits
Exact circuit configuration depends on the excavator specification.
Common Replacement Situations
Inspection, repair or replacement of the hydraulic main control valve may be considered when the machine experiences symptoms such as:
Hydraulic oil leakage · Abnormal actuator response · Weak hydraulic function · Irregular movement · Internal valve leakage · Sticking valve spool · Damaged valve body or ports
These symptoms can also be caused by hydraulic pumps, cylinders, motors, pilot valves, solenoid valves, sensors, hoses or hydraulic contamination. Professional hydraulic diagnosis is recommended before replacing the complete valve assembly.
Applications
Suitable for excavators working in:
Construction · Earthmoving · Mining · Quarrying · Road Construction · Demolition · Excavation · Equipment Rental · Heavy Machinery Maintenance
It is also suitable for excavator repair workshops, hydraulic repair companies and construction machinery spare parts distributors.
