Benefits
Pressure-Independent Flow Control
Unlike conventional control valves, the D997F automatically maintains the required flow rate regardless of pressure variations within the HVAC network. This ensures stable system performance and eliminates the need for continual balancing adjustments.
Built-in Energy Metering
Integrated temperature sensors calculate thermal power and energy consumption in real time, allowing facility managers to monitor system efficiency without installing separate energy meters.
Delta T Optimization
The D997F actively maximizes return water ΔT, improving chiller and boiler efficiency while reducing pumping energy and operating costs. Better ΔT also helps increase available plant capacity in large HVAC installations.
Smart Building Connectivity
Using Modbus RTU, the valve exchanges operational data directly with the Building Management System, enabling:
- Remote commissioning
- Real-time monitoring
- Flow verification
- Energy reporting
- Alarm and diagnostics
- Predictive maintenance.
Reduced Installation and Commissioning Time
Flow setpoints and operating parameters can be configured remotely through the BMS or Crane Configurator software, reducing commissioning time and minimizing on-site adjustments.
Typical Applications
The Crane D997F is ideal for:
- Commercial HVAC systems
- District cooling networks
- District heating systems
- Chilled water systems
- Air Handling Units (AHUs)
