| No. | Question | Answer |
|---|---|---|
| Q1 | Which equipment fits ZVEZDA 3330601 ETR fuel control actuator? | Direct replacement for QSK19 / QSK45 large PT pump diesel engines for mining trucks, generators and marine equipment, interchange OE numbers 3347906 / 3330600, 24V standard specification, thread cartridge plug-in installation without modification. Note: Only QSK19 can interchange with 3330600 series, QSK45 cannot mix with QSK60 dedicated actuators. Made in China, full stock, ship within 1-7 working days. |
| Q2 | Engine still surges and unstable idle after replacing this ZVEZDA ETR fuel actuator? | Original coil aging or metering spool wear leads to inaccurate fuel flow and fluctuating pump rail pressure, replace this full set ZVEZDA integrated ETR fuel control actuator to restore precise fuel metering and stable engine speed. |
| Q3 | Can this ETR fuel metering actuator replace excavator hydraulic proportional solenoid valve or engine fuel shutoff solenoid? | Not interchangeable, this ETR actuator is high-precision fuel flow control part for large diesel engine PT fuel pump; proportional valve adjusts excavator main pump torque, shutoff solenoid only cuts fuel circuit, different working medium, control logic and installation position. |
| Q4 | Core advantages of ZVEZDA 3330601 ETR electronic fuel control actuator? | ZVEZDA H-grade high temperature pure copper coil, ultra-precision multi-groove alloy metering spool, linear accurate fuel flow adjustment, multi-layer HNBR IP68 fuel-proof & dust-proof waterproof sealing, OEM standard cartridge thread for direct plug replacement, neutral unbranded packaging, perfectly match QSK19/QSK45 large diesel engine PT pump ETR fuel electronic control system. |
