M-BUS Smart Valve for HVAC Systems | Remote Temperature & Flow Control

Key Features

Superior Sealing & Durability: Features a valve stem with a three-layer sealing design to effectively prevent water leakage. The compact structure and IP67 protection rating ensure excellent waterproof performance and reliability in demanding environments.
Corrosion-Resistant Construction: The valve body and ball are crafted from high-quality brass, offering exceptional corrosion resistance and a significantly extended service life.
Flexible Installation: The valve controller and the valve body can be installed separately, providing greater flexibility and convenience during construction and retrofits.
Intelligent Anti-Seize Function: To prevent scaling or blockage from long periods of inactivity (e.g., during non-heating/cooling seasons), the controller can be programmed to automatically cycle the valve open and closed periodically.
Robust Data Communication: Utilizes the standardized M-BUS (CJT188-2004) protocol for long-distance, high-reliability communication with the data concentrator, simplifying system wiring and debugging.
Optional Temperature Sensing: Can be customized with the ability to collect and report both inlet and return water temperatures for more granular system analysis and control.

Working Principle

1. Centralized Command: The upper computer system sends commands (e.g., “Open Valve,” “Close Valve,” “Set Temperature”) to the M-BUS Concentrator.
2. Signal Transmission: The concentrator relays these commands to the specific Smart Valve Controller via the M-BUS communication lines.
3. Valve Actuation: The controller receives the instruction and actuates the brass ball valve to the desired position, regulating the flow of hot or chilled water.
4. Status Feedback: The valve controller continuously monitors its status (open/closed, fault conditions) and can upload this data back to the central management system for real-time monitoring and historical analysis.

Applications

• Central HVAC systems in commercial buildings and office complexes
• District heating and cooling systems for residential communities
• Smart home and building automation systems
