Product Overview

The Neles VD Series Pneumatic Linear Diaphragm Actuator, combined with the NDX Smart Valve Positioner, forms a high-precision control solution for industrial valves. Designed for modulating control and on-off service, this system excels in harsh environments with its stainless steel construction, IP67 protection, and HART/FF communication protocols.

Key Features
  • 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.
