Question & Answer
| No. | Question & Answer |
|---|---|
| Q1 | Q: Which excavators fit ZVEZDA 1006178 cartridge proportional valve? A: Direct replacement for Sany heavy H-series excavators SY375H/SY485H/SY550H large displacement main pump, interchange OE TM1006178, 24V standard, single flange cartridge install without modification. Made in China, full stock, ship within 1–7 working days. |
| Q2 | Q: Heavy excavator still surges and weak digging after replacement? A: Aging coil or worn plunger leads to unstable negative flow feedback pressure, replace complete ZVEZDA integrated cartridge proportional valve to restore stable high-pressure pump output and smooth machine operation. |
| Q3 | Q: Can this Sany heavy excavator proportional valve replace diesel engine SCV fuel valve or wheel loader transmission shift solenoid? A: Not interchangeable. This is hydraulic pressure regulating part for large excavator main pump; SCV valve adjusts diesel fuel pump intake flow, transmission solenoid only switches gearbox oil circuit, different working medium and control logic. |
| Q4 | Q: Core advantages of ZVEZDA 1006178 cartridge proportional solenoid valve? A: H-grade high temp pure copper uniform winding coil, ultra-precision multi-groove alloy plunger, linear stable negative flow pressure adjustment, multi-layer HNBR IP67 oil-proof & dust-proof waterproof sealing, OEM standard single-hole flange cartridge size for direct bolt replacement, neutral unbranded packaging, perfectly match Sany H-series heavy excavator main pump negative flow hydraulic control system. |
