  • High Thrust Output: Delivers 1,890-22,800 N (424-5,125 lb.f) for linear valve control.
  • Smart Positioning: NDX positioner with auto-tuning and ±0.5% accuracy.
  • Low Maintenance: Involute diaphragm design reduces friction and wear.
  • Explosion-Proof: ATEX/IECEx certification for hazardous areas.
  • Energy Efficient: Piezo valve technology minimizes air consumption.
