Axiom AN Series Valve Position Monitor
Brand: ValmetThe Axiom AN uses non-contact position sensing with solid state electronics and contaminant-tolerant pneumatic control.
Coupled with its space-efficient design, corrosion resistance and networking/Wireless Link capability, the AN is convenient and cost-saving benefits in hazardous and general-purpose process applications.
Features- Universal Voltage Solenoid System: Operates from 24 Vdc – 250 Vac at extended temperate range and features manual override. Single or dual coil available
- Fully Sealed Module: Solid state, fully potted sensors provide protection against residual moisture, vibration, and corrosives
- High Flow Pneumatic Valve: 5-way, 2-position valve operates on standard plant air. Rebreather prevents ingestion of contaminated air into actuator
- High Visibility Indication: Mechanical and electronic indication confirms open and closed position. Intense LEDs display position status from a distance
