Type AMI

valve communication and control deviceAdvanced high accuracy position sensor system

The type AMI Valve Communication & Control device incorporates an advanced high accuracy position sensor system with push button settings that may be made quickly and conveniently.

The integral pneumatic pilot valve operated by the universal burnout-proof solenoid (single or dual coil operation available) offers contemporary features which further enhance the operating performance of the automated valve system.

Features and Benefits

  • Corrosion-proof, temporarily submersible (IP67) and suitable for use in hazardous areas (Ex ia Intrinsic Safetyand Ex nA Non-Incendive).
  • High strength durable enclosure and pneumatic manifold are constructed of anodised aluminium and epoxy coated. Impact resistant cover of high strength polycarbonate and fasteners in stainless steel.
  • High visibility mechanical and electronic indication confirms the OPEN / CLOSED position and solenoid status for greater safety and convenience.
    Universal burnout-proof solenoid operates on less than 0.6 watts of power and standard version will accept either 24 VDC or 120 VAC supply.
  • Electronic sensing, switching and communication components are sealed and potted inside function module to protect against residual moisture, vibration and corrosives.
  • High accuracy position sensor system is solid state with no moving wear points for highly reliable and precise position feedback.
  • Push button set points for open & closed accurately lock in position settings. Settings remain locked in when power is removed and reapplied.
  • Integral pneumatic valve operates on standard plant air and will cycle most actuators in less than 2 seconds.
  • Wiring and maintenance access is quick and convenient for easy set-up and installation.
  • Internal manual pneumatic valve override is standard enabling local automated valve operation.
  • Standard 5-way 2 position valve operates both double & single acting actuators and features a re-breather to feed clean air to spring to keep out corrosives.
  • Simplified mounting arrangements allow quick and secure mounting to pneumatic actuators with VDI/VDE.3845 topworks as well as other actuators with non-standard topworks.
