5540482300 VALVE RELIEF

5540482300 VALVE-RELIEF ATLAS COPCO
Precision Relief Valve for Hydraulic Stability in Heavy Rock Drill Operations

---

In high-performance drilling systems, even the smallest component plays a critical role in ensuring efficiency, safety, and machine longevity. The 5540482300 VALVE-RELIEF ATLAS COPCO is a testament to that engineering precision. Specifically crafted for the demanding hydraulic environments of Atlas Copco heavy machinery, this relief valve offers consistent pressure control, system protection, and operational reliability in the toughest rock drilling scenarios.

Relief valves like the 5540482300 VALVE-RELIEF ATLAS COPCO are vital in hydraulic systems to prevent excess pressure from damaging pumps, hoses, and other components. Whether in underground mining, tunneling, or quarry drilling operations, stable pressure regulation is essential—not just for maintaining system health, but also for worker safety and optimal drilling performance.

Core Functionality & Performance

The 5540482300 VALVE-RELIEF ATLAS COPCO serves as a precision pressure relief mechanism. Its primary job is to act as a safety buffer—regulating the hydraulic pressure within a specified range. When the internal pressure exceeds a pre-set threshold, this valve temporarily opens to divert excess fluid, maintaining system balance and preventing mechanical failure.

Unlike general-purpose valves, this OEM-equivalent part from 3GEN Export is specifically engineered for compatibility with Atlas Copco hydraulic systems, ensuring seamless integration and dependable performance. Its cylindrical structure is robust, with O-rings and high-tolerance threading that allow it to withstand elevated pressures without leaks or deformation.
