Stonel™ Axiom™ AN / ANX

Highly reliable integrated discrete valve controller

Valve controller for on off applications with high intensity visual LED indication and optional advanced diagnostics

The Stonel Axiom provides advanced monitoring and control in explosionproof, nonincendive, intrinsically safe and general-purpose applications. It is a discrete on/off valve controller with proximity switches for quarter-turn automated valves. The rugged construction will withstand the most challenging plant environments. It features wireless capabilities, advanced diagnostics, and an integral solenoid valve in single or dual pilot configurations. Overall, the Axiom offers unrivaled convenience and cost savings in hazardous and general-purpose applications.

Benefits

Magnetic drive eliminates wear bushings and offers ultra-high reliability

Universal voltage reduces inventory and enables easy standardization

Quick and convenient set-up with push button switch setting

Robust enclosure tolerates most process environments

Features

  • Epoxy coated anodized aluminum enclosure (ANX)
  • Epoxy coated anodized aluminum housing with Polycarbonate cover (AN)
  • Universal voltage solenoid and switching
  • Convenient push button switch setting
  • Robust solenoid valve with standard rebreather
  • Optional wireless access for configuration and diagnostics
  • Advanced diagnostics with AS-interface (ASi-5). Diagnostics settings managed via Stonel Wireless Link app
  • Space efficient design
  • Rebreather system minimizes corrosive ingestion for single-acting actuators
  • Bluetooth wireless access versions enable convenient trouble-shooting to anticipate problems,  increasing plant uptime and reducing maintenance costs
  • Compact design minimizes valve-actuator assembly dimensional envelope

Integral pneumatics

  • Solenoid pilot drives the main high-flow spool valve
  • Pilots automatically associated with the appropriate function selected
  • Solenoid pilot and main spool design offer long life, exceptional tolerance to dirty air, and tight shut-off
  • Rebreather channels exhausted air from pressurized side of actuator into spring side, preventing ingestion of contaminated air from the environment that may corrode springs or actuator internals

Applications and functions

 
Control and monitor an automated on/off valve in all process areas
The Axiom monitors and reports valve position with Visual indicator and signals to the controller. Features integral single or dual coil solenoid valves to control position of the actuated valve.

Convenient switch setting
The touch sensors have no moving parts; just hold your finger for two seconds on the button to set. The bright LED indication confirms that you have successfully set the position. Communication models allow you to configure and set the sensors using your smart phone or tablet; no cover removal needed!
 
Single or dual pilot configuration
Available in either single or dual pilot configurations. Dual pilot options are available for shuttle piston, fail-in-last position applications. Several external manual override options are also readily available. For special valve configurations with nonstandard manual override features, please consult factory.
Reliable position sensing
An extremely reliable solid state magnetic resistive (mag res) sensor detects the valve position by monitoring the orientation of a magnet attached to the actuator. This design is tolerant of lateral and vertical shaft movement, which may occur in heavily used actuators, without affecting rotational measurement.
 
High-visibility LED indication
Clearly view valve position status with the high-visibility LED indicators. The LEDs offer easy viewing from a distance with the high intensity lighting that can be identified even in sunlight.

Networking with wireless link

Stonel products with AS-Interface and DeviceNet offer dramatic installation cost savings and have optional wireless link, compatible with Android and iOS devices. Units with wireless link are also available for conventionally wired systems and IO-Link. Wireless capabilities offer unrivaled convenience and maintenance savings during the automated valve’s entire life cycle. You may remotely access your valves from up to 50 meters, depending on obstructions.
