Danfoss 003N5006 Water Valve

As a key component for maintaining precise condensing pressure, the Danfoss 003N5006 (WVFX 10) is a pressure-operated water valve designed for water-cooled condensers in refrigeration and air conditioning systems. This self-acting modulating valve regulates water flow based on fluctuations in condensing pressure, ensuring the system operates within optimal thermal limits without the need for an external power supply. Built with a robust brass body, the Danfoss WVFX 10 water valve features a 3/8" NPT water-side connection and a 1/4" SAE flare refrigerant connection, making it high-performance and reliable for heavy-duty HVACR applications. The 003N5006 is technically identical to the 003N5007, serving as a dependable head pressure control valve that automatically shuts off water flow when the compressor stops. This model is compatible with a wide range of refrigerants, including HFCs and HCFCs, and is specifically engineered to handle fresh water and neutral brines with an orifice size of 10mm for precise modulating control.

• Automatic Head Pressure Regulation: Modulates water flow to maintain stable condensing pressure, protecting the compressor from surges.
• Self-Acting Operation: Entirely pressure-driven design eliminates the need for electrical wiring or control signals, simplifying installation.
• Resource Efficiency: Conserves water by providing the exact flow rate required and provides a absolute shut-off during down cycles.
• Hard-Duty Construction: Features a bellows element and double sealing to prevent refrigerant-to-water cross-contamination even if internal damage occurs.
• Broad Compatibility: Fully interchangeable with Danfoss 003N5007 and suitable for many modern refrigerants including R404A, R407C, and R410A (verify specific MWP).

What is the difference between Danfoss 003N5006 and 003N5007?
Technically, these two parts are identical. Both are WVFX 10 models with 3/8" NPT water connections and 1/4" flare pressure connections. You can use either code number for the same installation requirements.

What is the pressure range for this WVFX 10 valve?
This specific model generally operates within a control pressure range of 60 to 333 psig (4 to 23 bar), making it ideal for systems requiring high-side pressure stability.

Can this valve be used with brine?
Yes, the Danfoss 003N5006 is designed to handle both fresh water and neutral brine media, provided the temperature remains within the -13°F to 266°F range.
