1. Core Definition

TheDanfoss Control Valve Moduleis an integrated valve control unit developed by Danfoss, combining electric actuators, valve bodies, and intelligent control algorithms. It is designed for precise regulation of fluid (liquid or gas) flow, pressure, or temperature. Its modular design enables rapid installation and system integration, making it widely used in industrial automation, HVAC (Heating, Ventilation, and Air Conditioning), energy management, and other fields.

2. Key Functions

• Precision Control: Drives valve opening via electric actuators to achieve closed-loop control of flow, pressure, or temperature.

• Adaptive Regulation: Built-in PID control algorithms automatically adjust valve positions based on sensor feedback to maintain system stability.

• Remote Monitoring: Supports communication protocols like Modbus and BACnet for integration with Building Automation Systems (BAS) or Industrial IoT (IIoT) platforms.

• Fault Diagnosis: Real-time monitoring of valve status (e.g., opening, torque, temperature) with alerts or safety modes triggered during abnormalities.

• Energy Optimization: Reduces energy waste through dynamic regulation, such as adjusting chilled/hot water flow in HVAC systems based on indoor load.

5. Selection Guide

When selecting a Danfoss Control Valve Module, consider the following key parameters:

5.1 Technical Specifications

• Nominal Diameter (DN): Choose based on pipeline size (e.g., DN15-DN300).

• Pressure Rating (PN): Match system operating pressure (e.g., PN16, PN25).

• Flow Range: Select based on maximum/minimum flow requirements.

• Temperature Range: Adapt to medium temperature (e.g., -20°C to +180°C).

• Actuator Torque: Ensure the actuator can overcome valve resistance.

5.2 Control Requirements

• Control Precision: High-precision scenarios (e.g., laboratories) require regulating valves with excellent linearity.

• Response Speed: Fast-regulation scenarios (e.g., air conditioning water systems) need electric ball valves with short response times.

• Communication Protocol: Choose based on compatibility with existing systems (e.g., Modbus, BACnet).

5.3 Environmental Conditions

• Protection Level: Select IP65 or higher for outdoor or humid environments.

• Explosion-Proof Requirements: Choose Ex-certified models for flammable/explosive areas.

5.4 Additional Features

• Fail-Safe Mode: Valve automatically closes or opens during power failure (based on safety needs).

• Manual Operation: Supports on-site manual adjustment (for maintenance or debugging).

• Data Logging: Built-in memory for recording operational data (for fault tracing).

6. Installation and Maintenance

• Installation Requirements:

• Install vertically or horizontally to avoid actuator jamming due to tilting.

• Pipeline cleanliness must meet NAS 1638 Class 7 or higher to prevent valve damage from impurities.

• Commissioning Steps:

1. Verify actuator direction after power-on.

2. Set valve opening and feedback signal correspondence via the controller.

3. Simulate fault signals to validate safety mode activation.

• Maintenance Schedule:

• Inspect actuator lubrication and seals every 6 months.

• Replace valve internal filters annually (if applicable).
