| No. | Question & Answer |
|---|---|
| Q1 |
Q: Which Doosan medium excavators fit ZVEZDA DH220-5 main relief valve?
A: Direct replacement for Doosan DH220-5 medium excavators, standard cartridge size, directly insert into main valve block without modifying valve cavity. In stock, ship within 1–7 working days.
|
| Q2 |
Q: Excavator still weak digging and engine stall under heavy load after replacement?
A: Fatigued pressure spring leads to drifted relief pressure, replace complete ZVEZDA integrated main relief cartridge to restore standard main circuit pressure and normal digging power.
|
| Q3 |
Q: Can this main relief valve replace travel relief valve or unloading valve?
A: Not interchangeable. This high pressure hydraulic cartridge valve is used for main circuit overload protection; travel relief valve controls travel dedicated hydraulic pressure, unloading valve adjusts idle medium pressure, different medium, pressure range and working principle.
|
| Q4 |
Q: Core advantages of ZVEZDA DH220-5 main relief valve?
A: High strength alloy steel anti-wear spool, high fatigue resistant silicon manganese pressure spring, stable fixed relief pressure, double-layer HNBR high pressure anti-leakage sealing, full anti-rust precision ground cartridge body, OEM standard cartridge dimension direct replacement, neutral unbranded packaging, perfectly match DH220-5 main hydraulic overload protection system.
