Danfoss 003N2100 Water Valve

The Danfoss 003N2100 WVFX 15 is a pressure-operated water regulating valve designed for modulating flow in water-cooled condensers. This 1/2-inch G-threaded valve utilizes a brass body for superior corrosion resistance and features a bellows system that opens on rising condensing pressure. Engineered for high-pressure applications, the 003N2100 operates across a control pressure range of 3.5 to 16.00 bar (51 to 232 psig), making it ideal for systems using high-pressure refrigerants like R134a, R404A, R407C, and R513A. With a Cv value of 2.2 gal/min and a maximum working pressure of 232 psig, this valve ensures precise temperature control and stable condensing conditions. The unit includes a 1/4-inch SAE flare refrigerant connection and is compatible with neutral brines and fresh water. This pressure operated water valve is a standard-setting component for industrial cooling and water-cooled HVAC systems requiring robust, oil-free refrigerant compatibility.

Key Benefits for Contractors:

• Corrosion Resistance: High-grade brass valve body ensures longevity in harsh water environments and neutral brine systems.
• Precise Modulation: Facilitates exact flow regulation to maintain constant condensing pressure and optimize system efficiency.
• Refrigerant Versatility: Fully compatible with HFC and HCFC refrigerants, including modern A2L blends like R1234yf.
• Wide Operating Envelope: Handles media temperatures from -13°F to 266°F (-25°C to 130°C) for diverse industrial applications.
• Industry Compliance: Meets UL, C UL US, and PED standards for safe installation in regulated commercial projects.

Common Questions:

What is the primary function of the WVFX 15?
The Danfoss WVFX 15 is used to regulate water flow through a condenser based on the refrigerant pressure, ensuring the condensing pressure remains stable during operation.

Does the 003N2100 open on pressure rise or fall?
This specific water regulating valve is designed to open on a rising pressure signal from the condenser side.

Is the WVFX 15 compatible with glycol?
Yes, the brass construction and bellows design are rated for use with fresh water and neutral brine solutions, including glycol mixtures.
