Danfoss 003N6115 Valve

The Danfoss 003N6115 is a self-acting, thermo-operated water valve engineered for precise temperature regulation in demanding industrial and cooling applications. This AVTA 15 model features a 1/2" NPT connection and is designed to open on a rising sensor temperature. Built with a high-grade brass body, it ensures long-term durability in HVACR and hydraulic systems. The valve operates using an adsorption charge, making it highly responsive to temperature fluctuations across a wide media range of -13°F to 266°F. With a maximum working pressure of 232 PSI and a flow capacity of 2.2 GPM (Cv 2.2), this Danfoss temperature control valve maintains optimal thermal balance without the need for auxiliary power like electricity or compressed air.

Key Benefits

• Self-Acting Operation: Eliminates the need for external power, providing consistent cooling water regulation independently.
• Precise Flow Control: Proportional regulation ensures cooling media is only used when sensor temperatures rise, improving system efficiency.
• Robust Construction: The forged brass body and adsorption charge are built for high-pressure environments up to 232 PSIG.
• Versatile Mounting: This thermo-operated valve can be installed in any position to facilitate integration into existing piping.
• Universal Compatibility: Designed for neutral media and widely used in air compressors, plastic machinery, and refrigeration units.

Common Questions

Is this valve suitable for heating applications?
The Danfoss 003N6115 is specifically an AVTA cooling water valve that opens on rising sensor temperature. For heating applications where the valve needs to close on rising temperature, a different model in the AVTA series may be required.

Where should the sensor be installed for best results?
For accurate thermal regulation, the sensor should be placed where the temperature change is most critical. Using a sensor pocket (immersion well) is recommended to protect the bulb while ensuring heat transfer.

Can the capillary tube be shortened?
No, the 2300 mm capillary tube is part of a hermetically sealed thermostatic element. Cutting or kinking the tube will cause the charge to escape and render the valve inoperative.
