| No. | Question & Answer |
|---|---|
| Q1 | Q: Which excavator fits ZVEZDA 362-3212-06 proportional solenoid valve?
A: Direct replacement for 320E / 330E medium excavator main hydraulic pump, interchange OE 362321206, 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 0-5V PWM flow proportional valve for high-pressure excavator pump; brake solenoid only switches low-pressure oil circuit, fuel shutoff solenoid cuts diesel supply, different medium, pressure grade and control logic. |
| Q4 | Q: Core advantages of ZVEZDA 362-3212-06 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 direct replacement, neutral unbranded packaging, perfectly match 320E/330E excavator main pump hydraulic control system. |
