HTS Maxon Valves – Smartlink MRV Control Valves
Need help selecting your product?
The Honeywell Maxon SMARTLINK® MRV (Micro-Ratio Valve) combines the proven mechanical precision of Maxon’s Micro-Ratio control system with advanced SMARTLINK® DS digital actuation technology. This intelligent valve system delivers automated, repeatable, and finely tuned air/fuel ratio control for industrial burners and process heating systems. Designed for complete integration into modern combustion control architectures, the SMARTLINK® MRV provides high accuracy, data feedback, and reduced setup time compared to traditional linkage systems.
Features & Benefits
- Electronically controlled air/fuel ratio valve set with digital precision.
- Integrates SMARTLINK® DS actuator with Micro-Ratio air/fuel control body for fully automated modulation.
- Stores 1000 discrete actuator positions for smooth, repeatable ratio performance across the entire firing range.
- Available for air, gas, or oil service with M-, P-, and O-style body configurations.
- Communication-ready with 4–20 mA and Modbus RTU interfaces for command, feedback, and diagnostics.
- Factory-calibrated for plug-and-play installation—no mechanical linkages or cams required.
Model Overview
SMARTLINK® MRV configurations correspond to the legacy M (air), P (gas), and O (oil) mechanical valve bodies with integrated DS digital actuation.
| Configuration | Valve Sizes | Description |
|---|---|---|
| SMARTLINK® MRV-M | 1½″ – 18″ | Micro-Ratio Air Butterfly Valve with integrated DS actuator; precise air control for combustion systems. |
| SMARTLINK® MRV-P | ½″ – 2½″ | Micro-Ratio Gas Poppet Valve with DS actuator; adjustable gradient for modulated fuel flow. |
| SMARTLINK® MRV-O | ⅜″ – 2″ | Micro-Ratio Oil Valve with DS actuator; maintains stable fuel/air ratio under varying load conditions. |
