Short Description:

150602080013A021 Proportional Pressure Reducing Valve is core electro‑hydraulic component for Sany SY1350C1C3KH large excavator. It receives electric signal from controller and linearly adjusts output pressure of pilot circuit, controls main‑pump flow and actuator response to realize smooth operation of digging, slewing and travel. Assembly replacement is required in case of spool sticking, coil burnout, internal pressure relief or uncontrolled output pressure to guarantee precise and stable machine movements.

advantages

  • Electromagnet and spool match OEM parameters, output pressure varies linearly with electric signal, sensitive response without jamming and impact
  • Precisely‑machined valve body, resist contamination from hydraulic‑oil impurities, adapt to harsh high‑temperature and dusty mine‑site environment
  • Mounting holes and electrical connector specifications fully comply with OEM standard, direct installation without modification on harness and valve‑block base
  • Stable pressure feedback mechanism with high repeat control accuracy, reduce mis‑operation of pump‑valve assembly and extend service life of hydraulic components.

FAQ

Q: Can only spool be cleaned instead of full‑assembly replacement for abnormal output pressure?
A: If coil or valve sleeve are worn and damaged, spool cleaning only provides temporary improvement. Complete‑assembly replacement is recommended for heavy‑duty mine condition.
Q: Which parts should be checked firstly if movements remain abnormal after installation?
A: Inspect power‑supply harness, controller output signal and pilot‑oil cleanliness first, then judge whether valve body itself is defective.
