Premium Oem Negative Feedback Overflow Valve For Xcmg Hydraulic Systems *******95 *******2-4625

The *******95 *******2-4625 Negative Feedback Overflow Valve is a genuine XCMG OEM safety component designed to protect hydraulic circuits from overpressure while providing stable load-sensing feedback. Installed in the main control manifold of excavators, wheel loaders, motor graders, and cranes, this valve maintains system pressure at a preset maximum and returns excess flow to tank, preventing component damage and ensuring smooth operation under variable loads.

Crafted from hardened alloy steel with precision-ground spool and sleeve, the valve delivers reliable cracking pressure performance up to 25 MPa. Its negative-feedback design senses downstream pressure changes and modulates the orifice opening to stabilize pilot signals—enhancing load-holding capability and reducing pressure spikes during boom, bucket, or steering operations. The robust, corrosion-resistant body and high-quality seals ensure long-term durability in harsh jobsite environments.

Key Features & Benefits

• Overpressure Protection: Accurately relieves excess pressure to prevent hose, pump, and actuator damage

• Negative Feedback Stability: Automatically compensates for load changes to maintain consistent pilot pressure

• OEM Reliability: Factory-calibrated cracking pressure and fit for XCMG hydraulic manifolds—no adjustment needed

• Rugged Construction: Alloy steel body and premium seals resist wear, corrosion, and contamination
