HTS Maxon Valves – Smartlink DS Control Valves
Need help selecting your product?
The Honeywell Maxon SMARTLINK® DS Intelligent Control Actuator is a continuous-duty, maintenance-free digital actuator engineered for precise positioning and integrated valve control in combustion and process applications. It can be supplied as an actuator-only unit or factory-coupled to Maxon butterfly and ball valves, with options for AC or DC power, optional brake, optional display/keypad, and general-purpose or hazardous-location ratings.
Features & Benefits
- High-resolution positioning (up to 1000 points across 100° travel) for tight control and repeatability.
- Continuous-duty stepper drive with permanently lubricated planetary gearing for smooth, long-life operation.
- Optional electronic shaft brake to hold position on loss of power or torque exceedance.
- Wide operating temperature range and NEMA 4X/IP67 enclosure options for demanding environments.
- Analog 4–20 mA and Modbus communications for command/feedback, diagnostics, and health reporting.
- Available as stand-alone actuator or direct-coupled to Maxon butterfly/ball valves; linkages and couplings available.

Applications
Precision valve/actuator control for combustion air, fuel gas, steam, and liquids in ovens, furnaces, boilers, oxidizers, process heaters, and broader industrial process control where tight positioning, integrated diagnostics, and industrial communications are required.
Documentation
- Data Sheet – SMARTLINK® DS Intelligent Control Actuator technical catalog (models, configuration codes, specifications, dimensions).
Additional Information
- Use configuration codes to specify size, connection, body/seal materials, torque, power, area classification, and display/keypad options.
- Characterize ball-valve trim (slot/V/round) to match desired control curve and process turndown.
- Optional brake prevents drift on loss of power; select when fail-position holding is required.
- Diagnostics and alarm/lockout reporting support proactive maintenance and system reliability.
