Danfoss 003N2101 Water Valve

The Danfoss 003N2101 (Type WVFX 15 S.S.) is a high-performance, pressure operated water valve engineered specifically for modulating the flow of fresh water or neutral brine in water-cooled condensing units. This stainless steel water valve is an essential component for technicians maintaining high-side stability in corrosive environments or systems utilizing seawater cooling. With a 1/2-inch G connection and a Kv value of 1.9 m³/h (2.2 Cv), the WVFX 15 ensures precise condensing pressure regulation by opening on a rising refrigerant pressure. The bellows-operated design provides a control pressure range of 3.5 to 16 bar, making it compatible with a wide array of fluorinated refrigerants. Its double sealing between the refrigerant and water lines acts as a critical fail-safe, preventing cross-contamination even in the event of bellows fatigue. This self-acting, modulating water regulating valve operates without an external power supply, simplifying field installation and increasing system reliability for industrial refrigeration and commercial HVACR applications.

• Corrosion Resistance: The stainless steel housing is ideal for seawater applications and harsh environments where standard brass valves fail.
• Precise Pressure Control: Delivers linear modulation to maintain constant condensing pressure, optimizing compressor efficiency.
• Safety-First Design: Features a double-sealed bellows system to eliminate the risk of refrigerant leaking into the water circuit.
• Debris Tolerance: Engineered to be insensitive to dirt, reducing the frequency of maintenance calls for clogged internal orifices.
• Self-Acting Operation: Does not require electrical wiring, allowing for straightforward mechanical integration into any water-cooled system.

How do I adjust the opening pressure on the WVFX 15?
Technicians can adjust the setting by turning the internal adjustment screw. Rotating the screw clockwise increases the pressure required to open the valve, effectively raising the target condensing pressure of the system.

Can the Danfoss 003N2101 be used with seawater?
Yes. Unlike standard brass variants, the WVFX 15 S.S. model features a stainless steel body specifically designed to withstand the corrosive effects of seawater and neutral brines.

What is the maximum working pressure for this valve?
The WVFX 15 is rated for a maximum working pressure (PS) of 26.4 bar on the refrigerant side and 16 bar on the water side, with a maximum test pressure of 24 bar for the water circuit.
