20Y-60-22121 and 1700-2536 identify a two-position, three-way solenoid valve associated with Komatsu PC200-6 and 6D95 service. The catalog does not print a voltage on this product card, so the old valve marking and measured connector voltage must control selection.

Use the 20Y-60-22121 drawing to validate 7/8-14 dimensions, seal placement and two-position three-way flow paths without assuming a coil voltage.
Approve 20Y-60-22121 and 1700-2536 through measured coil voltage, 7/8-14 cartridge geometry, sealing lands, three-way circuit and PC200-6 serial data.
Approval Point |
Buyer Review |
Reference Control |
20Y-60-22121 / 1700-2536 |
Electrical Control |
Confirm from removed valve; verify at the connector under command |
Mechanical Fit |
Compare thread or flange, cartridge length, sealing lands and installed clearance |
Functional Control |
Confirm normal state, energized state and hydraulic port relationship |
Application Evidence |

When shifting is delayed, compare connector voltage, coil action, contamination, spool movement and the Komatsu valve-block response before ordering another unit.
Observed Situation |
Recommended Check |
No hydraulic response |
Check command voltage, connector, coil and whether the cartridge moves. |
Slow response |
Review oil cleanliness, filter condition, viscosity and connector voltage under load. |
Reversed response |
Compare normal and energized circuit states with the machine schematic. |
External leakage |
Inspect seals, cartridge surface, bore condition and seating depth. |
Repeated coil heating |
Check voltage, resistance, duty cycle, contamination and incomplete spool movement. |

The verified information does not establish one public voltage for every unit. Read the removed coil marking and measure connector supply during command before ordering. Keep the measured rating with 20Y-60-22121 on the RFQ and approved sample. Assigning an assumed voltage from another similar Komatsu cartridge can cause immediate coil damage or weak operation.
Use 1700-2536 as part of the reference group only when it appears with the removed assembly or equipment record. Confirm 20Y-60-22121, machine model, serial number, connector, cartridge interface and three-way function. The additional reference should improve traceability without replacing the physical evidence required for one approved PC200-6 configuration.
Compare cartridge length, sealing-land positions, nose profile, port openings and the normal and energized flow paths. Thread engagement cannot confirm hydraulic compatibility. A valve with different internal geometry may seat in the bore yet block a passage or reverse operation, so measurements and circuit comparison are required before commissioning.
Maintain filtration at 25 micrometres or better and investigate contaminated oil whenever switching becomes slow or inconsistent. Particles can score the spool, hold it between positions or damage seals during installation. Clean the cavity and protect the open cartridge before fitting; replacing the coil alone will not correct a dirty hydraulic system.
Send clear photographs of all markings, the coil voltage, connector face, cartridge and seals, plus overall and shoulder-to-land measurements. Include the Komatsu PC200-6 or 6D95 equipment record, serial number, required quantity and hydraulic symptom. Those details allow voltage and circuit approval without adding an unsupported specification.
Match the sample to measured machine supply and the old coil marking, then compare resistance, connector and controlled actuation. Verify three-way hydraulic response on the intended valve block and check for leakage after correct seating and torque. Record all results with 20Y-60-22121 so repeat orders use measured evidence rather than a transferred voltage claim.
Provide both references, Komatsu PC200-6 or 6D95 information, old coil marking, connector and cartridge photographs, measurements, quantity and destination.
