Precision Coating Valves | Dynamic Pressure Adjustment & Reduced Material Waste | NNT

Why Precision Matters in Industrial Coating
Uneven coating layers result in product defects, recalls, and compliance risks—particularly in regulated industries like aerospace or medical devices. Our [electrical proportional valves] solve these challenges through closed-loop pressure control that adapts to:

• Substrate Variations: Compensate for porous vs. non-porous materials instantly.

• Environmental Shifts: Auto-adjust for humidity/temperature-driven viscosity changes.

• Line Speed Fluctuations: Maintain ±3% thickness tolerance at 5–50 m/min.

Key Features Driving ROI

1. True Stepless Control
   Eliminate pressure spikes with 0–100% modulation granularity, critical for:

• Delicate electronics conformal coating

• High-speed food packaging film coating

2. Remote Process Optimization

• Adjust settings via HMI, SCADA, or [IoT-enabled coating software].

• Store 50+ coating recipes for rapid product changeovers.

3. Industry-Specific Certifications

• ATEX compliance for explosive environments (e.g., powder coating).

• FDA-grade materials for pharmaceutical/food contact surfaces.

how electro-pneumatic proportional valves revolutionize coating processes through:

1. Adaptive Pressure Profiling

• Real-time adjustment of fluidizing air pressure (0.5–10 bar) to match substrate geometries.

• 0.1-second response time eliminates overspray during speed changes.

• Pre-programmed recipes for gloss/matte finishes or multi-layer coatings.

2. Cross-Process Flexibility

• Single-valve compatibility with spray, dip, and roll coating systems.

• Auto-switching between high-viscosity (50,000 cP) and low-viscosity (<100 cP) materials.

3. IoT-Driven Efficiency

• Monitor coating thickness (±2µm) via integrated pressure-flow algorithms.

• Predictive maintenance alerts for nozzle wear or pressure drift.

• Energy savings up to 25% via demand-based compressor control.
