Danfoss 003N0108 Valve
The Danfoss 003N0108 is a heavy-duty AVTA 20 thermostatic cooling water valve designed for self-acting flow regulation in industrial and HVACR systems. Built for professionals who demand reliable temperature control without the need for auxiliary power, this valve utilizes a thirst-proof adsorption charge consisting of active carbon and CO2. This specific charge allows the valve to be installed in any orientation, regardless of whether the sensor is colder or warmer than the valve body. With a 3/4 inch G internal thread connection and a 20mm orifice, the Danfoss AVTA 20 provides a substantial Kv value of 3.4 m³/h, making it ideal for managing high-load cooling applications like vacuum pumps, compressors, and plastic molding machinery.
The integrated 2.3m capillary tube connects to a compact 9.5 x 150mm sensor, offering a wide regulating range of 10°C to 80°C. This self-acting water regulating valve operates on the principle of pressure changes within the element, opening the flow as the sensor temperature rises to maintain precise thermal equilibrium. The brass valve body is rated for a maximum working pressure of 16 bar and can withstand medium temperatures from -25°C up to 130°C. For technicians performing retrofits or new installs, the Danfoss 003N0108 ensures consistent performance in closed-loop or open-loop cooling circuits without the failure points typical of electronic solenoids.
Key Benefits- Universal Installation: The adsorption charge allows for mounting in any position, simplifying complex piping layouts.
- Mechanical Reliability: Operates without electricity, reducing wiring costs and eliminating risks from power surges or outages.
- High Thermal Tolerance: Designed to handle neutral media up to 130°C and sensor pressures up to 25 bar.
- Precise Proportional Regulation: Provides proportional flow control that adjusts the water volume based on real-time sensor demand.
- Field Serviceability: The thermostatic element can be replaced while the system is under pressure, minimizing downtime during maintenance.
Is the Danfoss 003N0108 compatible with glycol?
Yes, this Danfoss thermostatic valve is suitable for use with fresh water and neutral media, including ethylene glycol mixtures up to 40% concentration.
What is the difference between adsorption charge and universal charge?
The adsorption charge in the 003N0108 contains active carbon, allowing the sensor to be placed in any orientation. Unlike universal charges, it does not require the sensor bulb to be oriented in a specific way to function correctly.
How do I adjust the temperature setpoint?
Temperature is adjusted using the hand knob. Turning the knob counter-clockwise increases the temperature setting, while clockwise decreases it. A reference scale is etched into the spring housing for coarse adjustments.
