Danfoss 003N-6252 Temperature Regulator

The Danfoss 003N-6252 is a professional-grade AVTA thermostatic water valve designed for precise proportional regulation in industrial cooling applications. This 1/2" NPT temperature regulator operates on the closes on rise principle, meaning the valve opens as the sensor temperature increases to allow cooling media flow. With a flexible 70-140°F temperature range, it is an ideal solution for hydraulic oil cooling, air compressors, and localized heat exchangers. The bellows-operated design provides reliable pressure-neutral regulation, ensuring the flow rate remains consistent despite fluctuations in the primary supply pressure. Built with a robust brass body and a 6.5-foot capillary tube, the Danfoss AVTA 15 is engineered for high-vibration environments where electronic controllers might fail. This self-acting cooling water valve functions without manual intervention or external power, making it a critical component for maintaining thermal stability in heavy-duty HVACR systems and process loops.

• Proportional Regulation: Ensures cooling flow is matched precisely to the thermal load, reducing water waste and thermal shock.
• Self-Acting Operation: Operates entirely on the thermal expansion of the charge, requiring no electrical wiring or actuators.
• Insensitive to Pressure: Engineered to provide stable temperature control regardless of inlet pressure variations.
• Replaceable Thermostatic Element: Simplifies field maintenance by allowing for element swaps without removing the valve body from the piping.
• Universal Compatibility: The 1/2-inch NPT connections and wide setpoint range make it a standard replacement for many industrial temperature control valves.

How do I adjust the setpoint on the Danfoss AVTA valve?
The setpoint is adjusted by turning the calibrated knob at the top of the valve. For the 003N-6252, you can dial in the specific closing temperature between 70°F and 140°F based on your system's design requirements.

Can this valve be used for heating applications?
No, this specific model is a 'close on rise' (or open on rise for cooling) configuration. It is designed to mitigate overheating by opening a cooling line. For heating applications, a 'close on temperature rise' heating-specific regulator would be required.

What is the maximum pressure rating for the AVTA 15?
This Danfoss temperature regulator is rated for a maximum working pressure (MWP) of 232 psi (16 bar) and a maximum differential pressure of 145 psi (10 bar).
