- Chemical process
- Pharmaceutical and biotech
- Marine & offshore
- Oil & gas
- Agri-processing
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.

Single or double-acting configuration
The same Axiom AN model is suitable for both single-acting/spring return (SR) and double-acting (DA) actuators. The standard rebreather capability for single-acting/spring return is built in.
Field configuration may be made by conveniently removing and reinserting the pneumatic plug for the appropriate actuator type.
Universal application
The Axiom is designed to readily adapt to most quarter-turn actuators. The mounting manifold system combines the mounting base and pneumatic manifold to minimize space and simplify installation. It attaches the Axiom directly to the actuator and ports air from the pneumatic valve to the actuator.
Included in the manifold system are:
1. Actuator shaft adaptor and fastener.
2. Epoxy-coated anodized aluminum mounting plate manifold with o-rings and stainless steel fasteners.
3. Pneumatic plug for SR/DA configuration.
The manifold system readily adapts to VDI/VDE 3845 sizes 1, 2 and 3. Special variations may be made for sizes 3, 4 and non-standard quarter-turn actuator mounting patterns.
Proven sensing and communication
The Axiom platform has all position sensing, communication or switching integrated into StoneL C-module. Users may set open/closed positions conveniently and accurately on all modules. And easy to view instructions, along with bold LED indication, are displayed on the module itself.
Continuous sensing with open/closed settings
The C-module (continuous sensing) integrates a magnetic resistive sensor system to monitor exact valve position throughout the rotational range. Touch-sensitive or remote open and closed position setting along with microprocessor based operation make this state-of-the-art system convenient, reliable, and smart.
Position settings are made using the touch-sensitive buttons on the module’s overlay. Simply operate the actuator to the open position (using standard internal manual override) and touch the SET OPEN button. Operate the actuator to the closed position and touch the SET CLOSED button. Position settings remain locked in when power is removed and reapplied.
Networking with wireless link
Both the AS-Interface and DeviceNet models offer dramatic installation cost savings and have optional wireless link, with an iOS app. The wireless link is also available for conventionally wired systems. This feature offers 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.
Integral pneumatics
The Axiom’s pneumatic valve system consists of a solenoid pilot that drives the main high-flow spool valve. Pilots are automatically associated with the appropriate function selected.
Special features
- Solenoid pilot and main spool design offer long life, exceptional tolerance to dirty air, and tight shut-off.
- Universal voltage solenoid system may be used for standard AC or DC applications.
- Five-way, two-position spring return configuration may be used for either single- or double-acting actuators. Dual coil shuttle piston versions are also available for fail-in-last position.
- 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.
