PIL & PRL Proportional Valve | PIL400PC06 | PRL500PC10 | PIL500PC06 | Pressure Control Valve

PIL & PRL Series High-Performance Proportional Relief Valves

Product Overview:

The PIL and PRL series are precision electro-hydraulic proportional pressure control valves designed for sophisticated hydraulic systems. Utilizing high-efficiency proportional solenoids, these valves convert electrical input signals into proportional hydraulic pressure outputs. Available in compact PC06 (Size 6) and high-flow PC10 (Size 10) configurations, the series is renowned for its low hysteresis, high repeatability, and exceptional dynamic stability. These valves are critical for pressure regulation in injection molding, metal presses, CNC machinery, and high-end 2026 smart manufacturing lines.

Featured models: PRL500PC10P40, PIL400PC06P06, PIL500PC06P1, PIL400PC06P24, and PIL400PC06P30.

Key Technical Advantages:

• Precise Proportional Regulation: Achieves smooth, stepless adjustment from minimum pressure to rated levels (up to 300-400 bar).

• Tiered Sizing & Flow: Available in PC06 (NG6) and PC10 (NG10) to match various pilot or main circuit flow requirements.

• High Dynamic Response: Optimized spool design ensures rapid, shock-free pressure transitions even under severe load fluctuations, enhancing production efficiency.

• Superior Linearity: Minimal hysteresis ensures high consistency between the command signal and hydraulic pressure output.

• Robust Industrial Build: Constructed from high-strength materials and compatible with standard DC 24V amplifiers, offering excellent vibration and contamination resistance.
