| No. | Question | Answer |
|---|---|---|
| Q1 | Which equipment fits ZVEZDA 3347905 ETR fuel control actuator? | Direct replacement for large industrial diesel engines QSK19 / QSK38 / QSK50 / KTA50 used on mining trucks, generators and marine equipment, interchange OE numbers 3330600 / 3347907, 24V standard specification, thread cartridge installation without modification. 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 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 high-pressure 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 3347905 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/QSK38/QSK50/KTA50 large diesel engine ETR fuel electronic control system. |
