SAGAM-10/10/210 Atos Pressure Relief Valve 350bar

Product Overview:

The SAGAM series (including SAGAM-10, SAGAM-20, SAGAM-32, and AGAM10 configurations) consists of high-performance, two-stage pilot-operated hydraulic pressure relief valves designed to ISO 6264 subplate mounting standards. Engineered as a premium aftermarket solution for original Atos SAGAM and AGAM pressure control valves, this series delivers 100% direct drop-in interchangeability with zero subplate or piping modifications required. Featuring high-strength ductile iron bodies and micron-honed spool assemblies, SAGAM valves maintain precision pressure regulation, fast response, and exceptionally smooth solenoid-operated unloading under operational pressures up to 350 bar. Every valve undergoes 100% simulated full-load condition testing prior to shipment to guarantee leak-free performance and long-term industrial durability.

Key Technical Advantages

• 100% Direct Drop-in Interchangeability: Port configurations, mounting dimensions, and bolt patterns strictly align with ISO 6264 and original Atos factory specifications. Operators can execute direct field replacements instantly, minimizing machine downtime and installation labor.

• Balanced Two-Stage Design with Shock-Free Unloading: Precision-matched pilot poppet and main spool geometry ensure exceptionally fast response with stable pressure override. When integrated with solenoid venting, the valve delivers smooth system unloading without hydraulic shocks or line noise.

• Ductile Iron Body & Precision Honing: Manufactured from heavy-duty ductile iron resin-sand castings with hydrodynamically optimized internal passages. Spool and bore mating clearances are maintained at the micron level to minimize cross-port internal leakage and heat generation at 350 bar.

• 100% Full-Condition Simulation Testing: We do not rely on sample testing. Every single SAGAM valve is subjected to 100% automated bench testing under full system pressure (350 bar), maximum rated flow, and high-frequency solenoid switching to eliminate infant mortality and performance drift.

Application Areas

• Main safety relief and pressure regulating loops in industrial Hydraulic Power Units (HPUs)

• Multi-stage pressure control and unloader circuits in metal forging presses, die-casting, and injection molding machinery

• Heavy-duty hydraulic systems in metallurgical rolling mills, mining equipment, and mobile machinery

• Marine deck hydraulics and automated industrial pressing platforms

Expert Maintenance Tips

• Verify Mounting Surface Flatness: For reliable operation up to 350 bar, ensure the subplate mounting surface flatness is within 0.01/100 mm with a surface finish better than Ra 0.8. Surface irregularities cause uneven clamping stresses that can bind the internal spool or blow out base O-rings.

• Maintain Rigorous Fluid Cleanliness: Two-stage relief valves rely on small pilot damping orifices. System fluid cleanliness should be maintained at ISO 4406 class 19/17/14 (NAS class 8) or cleaner to prevent orifice clogging, pressure instability, or valve hunting.
