Atos AGAM Series Relief Valve | SAGAM Hydraulic Control Valve Replacement

Genlu Hydraulic proudly introduces our SAGAM Series (encompassing AGAM 20 and 10 frame sizes) high-performance pilot-operated relief valves. This series is engineered to be a seamless, high-value replacement for Atos AGAM series industrial hydraulic valves. Specifically optimized for stable pressure regulation, rapid response, and resilience against pressure spikes, our valves are the industry standard for precision hydraulic power units. Genlu guarantees 100% Drop-in Interchangeability in mounting geometries (conforming to ISO 6264 standards), pressure setting ranges, and electrical unloading interface specifications compared to original Atos components. Each SAGAM unit is validated through 100% simulation testing to ensure precise pressure-flow characteristics, securing long-term operational stability in complex hydraulic circuits.

Technical Specifications

• Product Series: Atos AGAM Pilot-Operated Relief Valve (Genlu SAGAM Series)

• Core Configuration Models: SAGAM-20/11/350 10S, SAGAM-20/210 53, SAGAM-10/10/210 10S

Key Technical Advantages:

• High-Precision Pilot-Stage Regulation: Features precision-ground pilot cones that minimize pressure fluctuation. The main valve responds smoothly even under rapid flow changes, eliminating acoustic resonance caused by pressure overshoot.

• Integrated Modular Solenoid Unloading: Engineered with a standard vent port interface, the valve is easily integrated with various solenoids to facilitate low-pressure standby modes, significantly improving overall machine energy efficiency.

• Heavy-Duty Cast Iron Construction: The valve housing is forged from high-stiffness ductile iron, optimized for high-stress relief applications up to 35 MPa. This minimizes structural micro-vibration, ensuring seal integrity and long service life.

• Industrial-Grade Corrosion Protection: Finished with an advanced anti-corrosion coating, our valves are built to maintain structural integrity and professional aesthetics even in harsh, humid, or oil-mist saturated industrial environments.

Application Areas:

• Industrial Hydraulic Power Units: Primary pressure control circuits for CNC machines, press brakes, and shearing machinery.

• Metal Forming Equipment: Holding pressure circuits for die-casting machines and overflow protection for large extrusion presses.

• High-Pressure Test Stands: Precision pressure regulation for hydraulic valve/pump testing rigs and performance loading circuits.

Expert Maintenance Tips:

• Enforce Strict Oil Cleanliness: Because the pilot valve stage relies on micron-level internal fits, particulate contamination is the primary cause of pressure instability or “creep.” Always utilize high-quality filtration (≤10µm) in the primary circuit.

• Regulated Adjustment Practices: Always adjust pressure settings while the system is under active flow. Do not overtighten the handwheel locking mechanism; excessive force can strip the adjustment threads.

• Proactive Seal Maintenance: Internal seals are subjected to significant thermal and pressure cycling. If system pressure becomes unstable or drifts, replace the internal seal kit promptly with high-grade Viton components to restore factory performance.
