Question & Answer
| No. | Question & Answer |
|---|---|
| Q1 | Q: Which excavator fits ZVEZDA 457-9897 proportional solenoid valve? A: Direct replacement for 320GC / 330GC medium excavator main hydraulic pump, interchange OE 4579897, 24V standard voltage, thread cartridge install without modifying pump valve block. In stock, ship within 1–7 working days. |
| Q2 | Q: Excavator still surges and slow arm movement after replacement? A: Aging coil or worn metering plunger leads to unstable pump flow output, replace complete ZVEZDA integrated cartridge proportional valve to restore stable hydraulic flow and normal digging performance. |
| Q3 | Q: Can this main pump proportional valve replace loader brake on-off solenoid or engine fuel cut solenoid? A: Not interchangeable. This is 0-5V PWM flow proportional valve for excavator hydraulic pump; brake solenoid only switches oil circuit, fuel shutoff solenoid cuts diesel supply, different working medium and control logic. |
| Q4 | Q: Core advantages of ZVEZDA 457-9897 cartridge proportional solenoid valve assembly? A: H-grade high temp pure copper uniform winding coil, precision multi-groove alloy metering plunger, linear stable pump flow regulation, multi-layer HNBR IP67 waterproof sealing, OEM standard cartridge thread size direct bolt replacement, neutral unbranded packaging, perfectly match 320GC/330GC excavator main pump hydraulic control system. |
