Danfoss 003N0041 Temperature Regulator

The Danfoss 003N0041 is a high-performance AVTA 15 thermostatic water valve engineered for proportional flow regulation in industrial and commercial HVACR cooling systems. This self-acting water regulator utilizes an adsorption charge to modulate flow based on sensor temperature, operating without the need for external power or compressed air. With a 2.2 Cv capacity and a 1/2-inch connection, this proportional temperature control valve is ideal for maintaining consistent medium temperatures between 25-65°C (77-149°F). The brass body construction and pressure-relieved design ensure that the valve’s opening degree remains independent of differential pressure, providing stable performance even in volatile systems. Designed for neutral media like water, air, or oil, the Danfoss AVTA 15B effectively prevents unnecessary cooling water consumption, maximizing system efficiency in processes such as hydraulic oil cooling, plastic molding, or compressor temperature management.

• Self-Operating Accuracy: Requires no electrical wiring or pneumatic air supply, reducing installation complexity and energy overhead.
• Pressure-Independent Regulation: The internal bellows design ensures that fluctuations in water pressure do not impact the precise temperature setpoint.
• Maintenance-Free Reliability: Built with a dirt-resistant design and a hermetically sealed thermostatic element to prevent debris adherence and internal leakage.
• Wide Application Range: Capable of handling medium temperatures up to 130°C and a maximum working pressure of 232 psig.

Is the AVTA 15 valve compatible with aggressive media?
This specific model features a brass body designed for neutral media. For aggressive applications like seawater or chemical processing, a stainless steel version (AVTA SS) is recommended.

Should the valve be installed on the supply or return line?
The valve can be installed on either the flow or return line, though mounting on the return line is common to minimize the mechanical stress from thermal shock on the sensor.

Does the valve close or open on a temperature rise?
The 003N0041 is designed to open as the sensor temperature increases, allowing more cooling medium to flow as the system heats up.
