A complete control bank and a cartridge are different orders
Replacing a full bank means buying the selected body and spool arrangement. A relief cartridge replaces one pressure-control component in the retained bank. Specify the operating function and installed number before comparing a bank price with a cartridge price.
| Valve | Function | Quoted assembly |
|---|---|---|
| Main control bank | Routes flow to boom, arm, bucket, travel and swing | Complete selected bank and controls |
| Pilot control valve | Commands a main spool | Pilot lever/pedal or valve unit |
| Overload/relief cartridge | Controls pressure at one position | Individual cartridge and its seals |
| Solenoid valve | Switches a commanded hydraulic function | Coil, cartridge or complete valve |
YN22V00002F9 is an overload-valve assembly
The CNH YN22V00002F9 entry is an overload valve. Its shipping package is95 ×52 ×52mm and0.469kg, with one assembly per package. It belongs on a pressure-control purchase line, distinct from a complete main-valve bank.
| Field | YN22V00002F9 |
|---|---|
| Product | Overload valve assembly |
| Order unit | One valve |
| Shipping package | 95 ×52 ×52mm |
| Packaged weight | 0.469kg |
Pilot and main valve numbers describe different components
702-16-03530 appears in the Komatsu PC200LC-8 pilot-control parts list as a PPC valve. The Cat6I-6899 is a legacy valve-group number for older320/325/330-series excavator entries. Keep the installed control position with either number; a PPC valve and a main bank are not the same assembly.
Ports, spool function and control voltage belong on the specification
For a complete bank, record the inlet and tank ports, actuator sections and pilot/control arrangement. For a cartridge, record the cavity/thread, sealing positions and set-pressure requirement. For a coil, give rated voltage, connector and coil code separately from the cartridge.
| Item | Technical purchase data |
|---|---|
| Bank | Valve-group number, spool sections, inlet/tank and actuator ports |
| Cartridge | Cavity/thread, seal positions, function and pressure setting |
| Pilot unit | PPC number, port arrangement and lever/pedal form |
| Solenoid coil | Voltage, connector, coil code and retained cartridge |
Pack a valve repair with its connecting seals
A replacement cartridge can travel with its seal set; a complete bank can include the required hose/pipe connection seals. Keep adapters and hoses as separate identified lines, especially on an order containing several machines.
Buying questions
Does an overload-valve price describe a whole control bank?
No. YN22V00002F9 is an overload-valve assembly. A full main bank includes its selected body and spool configuration.
Which voltage is needed on a solenoid order?
Use the installed coil voltage and connector code. The hydraulic cartridge has its own function and fitting identity.
Why does a relief cartridge need its pressure setting?
The valve controls pressure at an assigned circuit position. Its function and setting belong with the cavity/thread and sealing dimensions.
Can I replace only the coil?
A coil-only purchase retains the installed hydraulic cartridge. A complete solenoid-valve purchase identifies both the electrical and hydraulic components.
