Product Overview
The EATON 1ARC100P20S / 407AA00151A is a high-performance proportional pressure relief cartridge valve engineered by Eaton (Vickers) for precise electro-hydraulic pressure control in demanding industrial circuits. Operating on a direct-operated, poppet-and-spool principle, this cartridge-style valve modulates system pressure proportionally to an electrical command signal supplied to its integrated proportional solenoid. Unlike conventional fixed-setting relief valves, the 1ARC series enables continuous, infinitely variable pressure adjustment, making it ideal for systems requiring dynamic pressure profiling, soft-start/stop ramps, and closed-loop force or torque regulation. Its compact two-port cartridge design allows direct installation into a manifold cavity, reducing leakage paths and simplifying hydraulic power unit architecture.

Engineering Features & Advantages
- Precision Proportional Control: Infinitely variable pressure setting via proportional solenoid, enabling accurate pressure ramping and closed-loop regulation without mechanical adjustment.
- Fast Dynamic Response: Optimized spool geometry and low-inertia solenoid armature deliver rapid response times suitable for high-cycle industrial motion control.
- Cartridge Construction: Two-port slip-in cartridge design minimizes external leak paths, reduces manifold complexity, and allows high-density valve stacking in compact power units.
- Industrial Reliability: Built for continuous operation under severe industrial conditions with hardened metering edges and contamination-tolerant clearances.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Vickers 1ARC series cavity and electrical interface standards.
Typical Industrial Applications
This proportional pressure relief cartridge valve is widely deployed in plastic injection molding machines for clamp and injection pressure profiling, metallurgical presses requiring programmable force control, CNC machine tools with hydraulic tool clamping and counterbalance circuits, and construction or marine hydraulic systems where remote electronic pressure adjustment is critical. It is also commonly used in test stands and fatigue testing equipment demanding precise, repeatable pressure regulation.
