|---|---|
| Q1 |
Q: Which excavators fit ZVEZDA 1017969 proportional valve?
A: Direct replacement for Sany 10-series SY215/SY235/SY335 with KMX main pump, interchange OE TM90501 / 1017628 / 1013365, 24V standard specification, single-hole flange cartridge bolt installation without modification. Made in China, full stock, ship within 1–7 working days.
|
| Q2 |
Q: 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 proportional valve to restore stable pump pressure and smooth machine operation.
|
| Q3 |
Q: Can this Sany excavator negative flow proportional valve replace diesel engine SCV fuel valve or wheel loader transmission shift solenoid?
A: Not interchangeable, this valve is hydraulic pressure regulating accessory for 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 1017969 pressure reducing proportional solenoid valve?
A: ZVEZDA H-grade high temperature pure copper uniform winding coil, 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 10-series excavator main pump negative flow hydraulic control system.
