StoneL Valve Position Monitor, AMI Series
The Axiom AMI integrates solid state continuous sensing and pneumatic control to give long life and reliable performance in process applications.

The AMI also features the capability for intermediate valve control and diagnostics to offer more cost saving benefits.
Features
  • The Axiom is corrosion proof, temporarily submersible and suitable for use in hazardous areas. Designed for NEMA 4, 4X & 6; (IP67) Class I & II Div 2 nonincendive (Ex nA, Zone 2) and Class I & II Div 1 & 2 (Ex ia, Zones 0, 1, & 2) Intrinsically Safe
  • Universal Voltage Solenoid System operates on less than 0.6 watts of power and is burn out proof. Standard version will accept 24 Vdc, 120 Vac or 240 Vac, reducing stocking requirements
  • Standard 5-way, 2-position valve operates both double and single-acting actuators and features a rebreather to feed instrument air into spring side of actuator to keep out corrosives
  • High accuracy position sensor system is solid state with no moving wear points for highly reliable and precise position feedback
  • Integral pneumatic valve operates on standard plant air and will cycle most actuators in less than two seconds
