NNT NITV Series Electro-Pneumatic Proportional Valves enable continuous, stepless air pressure regulation via electrical signals, ideal for automation, packaging, and medical applications. Key features:
High Precision Control
Sensitivity: 0.2kPa (at 100kPa), linearity ±1% FS, hysteresis ≤0.5% FS.
Built-in pressure sensor with real-time feedback and rapid control-loop correction for dynamic stability.
Diverse Series Options
NITV0000 Series: Ultra-compact (15mm thick, 100g), 10-valve manifold support, 0.1s response (no load), LED error indication.
NITV2000/3000 Series: Positive pressure control (e.g., 0.005-0.9MPa), zero air consumption in standby, short-term pressure retention post power-off, analog/switch monitoring outputs.
Robust Performance
Operating temp: 0-50°C, IP65 rating, contamination-resistant (nozzle-flapper-free design).
Supports CC-Link, DeviceNet, PROFIBUS DP for seamless industrial network integration.
Installation & Maintenance
Requires 5μm filter and oil separator upstream; oil misters prohibited.
Power/air supply must start/stop simultaneously to prevent noise or lifespan reduction; exhaust residual pressure via 3-way valve.
