Danfoss 003N-7032RA Temperature Regulator

The Danfoss 003N-7032RA is a professional-grade AVTB-RA 20 thermostatic valve designed for precision temperature control in industrial cooling and process applications. Built with a rugged forged brass valve body, this self-acting regulator eliminates the need for external power or compressed air, making it an ideal choice for contractors looking for reliability in district cooling, heat exchangers, and hydraulic oil cooling systems. It features a 3/4" NPT internal thread connection and is specifically configured to open on temperature rise, ensuring consistent flow modulation as sensor thermal loads increase. Operating within a regulation range of 32°F to 86°F (0°C to 30°C), the 003N-7032RA utilizes a 2-meter capillary tube to deliver accurate feedback to the bellows, maintaining system stability across a maximum differential pressure of 145 psi. For technicians, the linear flow characteristics and 3.4 m³/h Kvs value provide predictable performance in both return lines and flow lines, ensuring peak operating economy for your client's HVACR infrastructure.

• Self-Acting Operation: Functions entirely on vapor pressure, requiring no electrical wiring or actuators for installation.
• Precise Flow Control: Linear characteristics ensure the flow change is proportional to the sensor temperature change.
• Extreme Durability: Pressure-relieved design ensures the opening degree remains unaffected by fluctuations in differential pressure.
• Broad Compatibility: Suitable for fresh water, neutral brine, and glycolic water solutions up to 30%.
• High Pressure Resilience: Rated for a maximum working pressure of 232 psi with a test pressure capacity up to 365 psi.

Does this valve require a specific mounting orientation?
While the valve body can be installed in any position, it is best practice to install the sensor in an area where the media flow is consistent. For this model with a vapor charge, the sensor must be oriented so that the capillary tube connection faces upwards to ensure proper response.

Can the 003N-7032RA be used for heating applications?
No, this specific model (RA suffix) is designed to open on rising temperature, which is the standard requirement for cooling and relief applications. For heating systems requiring the valve to close on temperature rise, a standard AVTB series valve should be selected.

What is the maximum media temperature this regulator can handle?
The valve body is rated for media temperatures up to 266°F (130°C), though the sensor itself should not exceed 131°F (55°C) to maintain the integrity of the thermostatic element and charge.
