Danfoss 003N6006 Valve

The Danfoss 003N6006 is a heavy-duty, pressure-operated WVFX-15 water regulating valve designed to optimize condensing pressure in water-cooled refrigeration and air conditioning systems. Engineered for precision, this 1/2 inch NPT water valve modulates flow based on refrigerant pressure, ensuring consistent system performance even during fluctuating load conditions. This specific model operates within a robust control pressure range of 60 to 338 psig (4 to 23 bar), making it a versatile choice for a wide variety of industrial and commercial condensing units. Its self-acting design means it requires no external power supply, utilizing a bellows system to provide a direct response to rising head pressure.

Constructed with a durable brass body, the Danfoss 003N6006 is compatible with fresh water and neutral brine media. It features a 1/4 inch SAE flare refrigerant connection and is rated for a maximum working pressure of 232 psig on the water side. Technicians often select the WVFX-15 for its reliability in maintaining head pressure and its ability to completely shut off water flow when the compressor cycles off, preventing unnecessary water consumption. This valve is fully compatible with standard HCFC and HFC refrigerants, including R22, R134a, R404A, and R410A.

• Precise Pressure Regulation: Maintains stable condensing pressure between 60-338 PSI to improve overall system efficiency.
• Universal Compatibility: Identical to the industry-standard WVFX-15, featuring 1/2" NPT water connections for straightforward retrofitting.
• Self-Acting Operation: Eliminates the need for electronic controllers or wiring by utilizing the system's own refrigerant pressure.
• Water Conservation: Automatically terminates water flow when the plant stops, reducing utility costs and environmental impact.
• Durable Construction: High-grade brass body and bellows system provide long-term resistance to harsh mechanical room environments.

Common Questions

Is the 003N6006 compatible with seawater applications?
No, this brass-bodied version is intended for fresh water and neutral brine. For seawater applications, a stainless steel version of the WVFX series should be utilized.

How do I adjust the opening pressure on this valve?
The opening pressure is adjusted via the setting spindle. Turning the spindle clockwise increases the opening pressure, while counter-clockwise decreases it within the 60-338 PSI range.

What is the maximum flow capacity (Cv) for this model?
The WVFX-15 (003N6006) has a flow coefficient of approximately 2.2 Cv (1.9 m³/h), making it suitable for small to medium-sized water-cooled condensers.
