| No. | Question | Answer |
|---|---|---|
| Q1 | Which equipment fits 9218234 24V flange proportional solenoid valve? | Direct replacement for medium crawler excavators, OE number 9218234, 24V standard specification, two-hole flange bolt mounting without modification. Made in China, full stock, ship within 1-7 working days. |
| Q2 | Machine still surging and hydraulic fault code pops up after replacing this torque proportional valve? | Original coil aging or spool surface wear leads to poor proportional linearity and unstable pump torque output, replace this full set integrated flange proportional valve to restore stable power matching between engine and main pump. |
| Q3 | Can this main pump torque proportional solenoid valve replace swing brake solenoid valve or engine accelerator motor? | Not interchangeable, this proportional valve is dedicated torque adjustment hydraulic component for main pump power matching; swing solenoid controls rotary brake oil circuit, throttle motor adjusts engine fuel supply, different structure, installation position and control logic. |
| Q4 | Core advantages of 9218234 proportional solenoid valve? | H-grade high temperature pure copper coil, multi-groove precision wear-resistant alloy spool, consistent full-range torque proportional linear output, multi-layer HNBR IP67 oil & dust waterproof sealing, OEM standard two-hole flange for direct bolt replacement, neutral unbranded packaging, perfectly match medium crawler excavator main pump negative flow torque control hydraulic system. |
