FAST LINKS

The Axiom (AMI) is a discrete valve communication and control device for quarter-turn automated valves (patent pending.) Its advanced position sensor offers reliable long life performance with push-button settings that may be made quickly and conveniently.

The integral pneumatic pilot valve offers contemporary features which further enhance the operating performance of your automated valve system. And, the Axiom’s rugged construction will withstand your most challenging plant environments.

Axiom Expeditor	Axiom with Diagnostics

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) and Class I & II Div 1 and 2 (Ex ia) Intrinsically Safe.
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.
High visibility mechanical and electronic indication confirm OPEN/CLOSED position and solenoid status for greater safety and convenience.
Universal burn out proof solenoid operates on less than 0.6 watts of power and standard version will accept either 24VDC or 120VAC, reducing stocking requirements.
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 five way, two position valve operates both double and single-acting actuators and features a re-breather to feed instrument air into spring side of actuator to keep out corrosives.
Axiom directly attaches to VDI/VDE 3845 (Namur) sizes 1 & 2 actuator accessory patterns and may be readily adapted for other actuator applications.

Pneumatic Control

The Axiom’s pneumatic valve system consists of a low power pilot that drives the main high flow spool valve. Pilots may be selected for conventional, intrinsically safe or bus networking applications. Both stages of the pneumatic valve system have been designed for long life, high tolerance to air line contaminants and ease of maintenance should components become fouled. <<More>>

Sensing and Communication Module

Open and Closed Settings Switches correspond to a particular valve position and are set using the push button panel on the module’s sealed membrane pad. Simply operate the actuator to the open position (using standard internal manual override) and push the “Set Open” button. Operate the actuator to the closed position and push the “Set Closed” button. Position settings remain locked in when power is removed and reapplied. <<More>>
