For Xcmg Original Port Overflow Valve For Construction Machinery Parts For Komatsu Pc200 Xe215 Xe215c Xe150d *******78 X0v25.40

The XCMG *******78 Port Overflow Valve, also known by model code X0V25.40, is a heavy-duty hydraulic control component used in high-performance excavators and construction machinery. This overflow valve plays a vital role in protecting the hydraulic system by safely discharging excess pressure from the circuit, thereby preventing system damage and ensuring consistent equipment performance.

     Made from precision-machined, heat-treated alloy steel, the valve body provides exceptional strength, wear resistance, and longevity even under continuous high-pressure operation. Internally, the X0V25.40 valve features a finely tuned spool and spring assembly that reacts quickly to pressure surges—ensuring smooth operation and minimizing hydraulic shock.

Key functions of this port-type overflow valve include:

• Maintaining stable pressure in hydraulic loops

• Preventing system overloads by releasing excess fluid

• Ensuring longer service life for main hydraulic components like pumps, cylinders, and control valves

• Improving operational efficiency by reducing fluid turbulence and pressure spikes

     This valve is fully compatible with a wide range of XCMG excavators, particularly in the 20–25-ton class, including:

• XE215, XE215C, XE230, XE150D, XE265D

     Due to its standardized port dimensions, pressure settings, and control response, it is also used interchangeably in excavators from other leading brands:
