Axiom AMI Valve Communication & Control

Axiom AMI Valve Communication & Control
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.

Axiom AMI Advanced Performance

The AMI features StoneL’s non-contact continuous position sensing system which eliminates shafts, bushings, and wear parts prone to failure. It also has an o-ring sealed pneumatic valve spool with pilot that is tolerant of contaminants found in most process plant air systems. The result of these design features is consistent reliable performance over the life of the automated valve system.

Wide Variety of Functions

offer exceptional value Select from standard SST sensors for conventional switching, NAMUR sensors for intrinsically safe applications or a broad array of communication options including AS- Interface, DeviceNet™ and Foundation Fieldbus. The Expeditor version provides the capability to offer additional value for special filling and flow dampening applications with intermediate control. And maintenance costs may be reduced using the diagnostic systems available with AS-Interface or in conventional 4-20 mA applications with the HART protocol.

Corrosion-Resistant

The AMI features an anodized epoxy-coated aluminum housing with a Lexan® cover to withstand corrosive process environments. The Lexan® cover may also be optionally fusion coated for organic solvents. Or an aluminum cover may be selected for special highly corrosive applications.

Axiom AMI Features

  1. 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.
  2. High strength durable enclosure and pneumatic manifold are constructed of anodized aluminum and epoxy coated. Impact-resistant cover is made of high strength Lexan® polycarbonate. All fasteners are stainless steel.
  3. High visibility mechanical and electronic indication confirm open and closed position and solenoid status for greater safety and convenience.
  4. 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.
  5. Electronic sensing, switching and communication components are sealed and potted inside function module to protect against residual moisture, vibration and corrosives.
  6. High accuracy position sensor system is solid state with no moving wear points for highly reliable and precise position feedback.
  7. Push button set points for open and closed accurately lock in position settings. Settings remain in place when power is removed and reapplied.
  8. Integral pneumatic valve operates on standard plant air and will cycle most actuators in less than two seconds.
  9. Wiring and maintenance access is quick and convenient for easy set-up and installation.
  10. Internal manual pneumatic valve override is standard enabling local automated valve operation.
  11. 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.
  12. Axiom directly attaches to VDI/VDE 3845 (NAMUR) actuators and many others using a compact mounting manifold system (sold separately).
