Q: Are 702-21-07610 and 702-21-07630 interchangeable?
A: These two solenoid valves are often used together on the same pilot control manifold but may have different internal flow characteristics or connector orientations. Always verify the specific location (e.g., boom up vs. arm in) before replacement. Purchasing them as a matched pair ensures complete pilot circuit reliability.
Q: What Komatsu excavator models use the 702-21-07610 and 702-21-07630 valves?
A: These valves are widely used across Komatsu PC series excavators including PC200-7, PC200-8, PC220-7, PC300-7, PC350-7, and PC400-7 models. They control pilot oil flow to the main control valve for smooth implement operation.
