Danfoss 003N2162 Valve

The Danfoss 003N2162 AVTA 15 is a self-acting thermostatic water valve engineered for precise proportional regulation in cooling applications. Designed for HVACR professionals, this 1/2 inch AVTA-15 valve utilizes a universal charge sensor to modulate flow based on temperature fluctuations without requiring external power or compressed air. With a regulation range of 25-65°C (77-149°F), the valve opens effectively on rising sensor temperatures, making it a reliable solution for condensers, processing machinery, and heat exchangers. Its forged brass body is built to withstand a maximum working pressure of 16 bar (232 psig) while remaining insensitive to dirt and pressure variations, ensuring consistent performance even in demanding environments. This specific model features a 2.0-meter capillary tube and an 18mm x 210mm sensor, providing the versatility needed for diverse installation configurations.

• Self-operating design eliminates the need for electrical wiring or pneumatic air lines, reducing installation complexity and long-term maintenance.
• Precise temperature control is maintained through a force-compensated spindle, preventing cooling medium fluctuations.
• Dirt-resistant construction ensures the valve cone remains operational in systems where particles or mineral deposits are present.
• Flexible mounting allows the valve body to be installed in any orientation, provided the flow follows the embossed arrow.
• Proportional regulation optimizes water consumption by only allowing flow when cooling is strictly required.

Is a bypass line required for this valve?
Yes, in many cooling applications, a bypass line is recommended to ensure the sensor can detect temperature changes during system startup when the valve may be closed.

Can this valve be used with glycol?
The AVTA 15 is compatible with neutral media, including water and ethylene glycol mixtures up to a 40% concentration.

How do I adjust the temperature setpoint?
The setting is adjusted using the plastic hand knob; turning it counter-clockwise increases the temperature setpoint, while clockwise decreases it. Using a thermometer near the sensor is advised for fine-tuning.
