FAQ


Q: Which failure symptoms indicate the priority valve needs urgent replacement?
A: If your ZX200 experiences sluggish swing movements or inconsistent boom speed while traveling, the 4723238 valve may be stuck or worn. Diagnostic pressure drops at the pilot port often confirm internal bypass issues.
 
Q: What are the critical installation technical requirements?
A: System flushing is mandatory to remove contaminants before installing the new 4723238 assembly. Always replace the O-rings and use a calibrated torque wrench to prevent housing distortion during mounting.
 
Q: How do I ensure procurement compatibility for various Hitachi generations?
A: This valve is engineered for ZX-series and EX-200-series. Please verify your machine's hydraulic schematic; while the external body looks similar to others, the internal spring tension of the 4723238 is specific to these tonnage classes.
 
Q: How does this valve perform under extreme environmental conditions?
A: Designed for mining and heavy construction, the valve maintains stable viscosity-flow ratios from -25 to 100 Celsius. The internal components are treated to resist thermal expansion, preventing "valve sticking" during 24/7 high-heat operations.

 

Q:  What quality options are available?

A: We provide original, OEM, and high-quality aftermarket versions with stable supply capability.
