Danfoss 003F1240 Water Pressure Valve

The Danfoss 003F1240, also identified as the WVFX-40, is a heavy-duty water regulating valve designed for condensing pressure control in medium-to-large-scale refrigeration systems. Featuring 1 1/2" G threaded connections, this pressure-operated valve maintains a consistent condensing pressure by modulating the flow of cooling water or neutral brine. It is compatible with a wide range of primary refrigerants including R22, R134a, R404A, R407C, and R507. The robust bellows construction ensures reliable modulation even in high-demand industrial environments. With an adjustable opening pressure range typically between 3.5 to 16 bar, the WVFX 40 is essential for optimizing system efficiency and preventing head pressure fluctuations. This unit functions as a direct replacement for Danfoss 003F124000, providing seamless integration into existing HVACR piping layouts where precise flow regulation and thermal stability are critical for compressor longevity.

• Precise Pressure Modulation: Automatically adjusts cooling water flow based on refrigerant pressure to maintain stable condensing levels.
• Broad Refrigerant Compatibility: Designed to work with HCFC and HFC refrigerants, ensuring versatility across various plant configurations.
• Durable Bellows Design: High-quality bellows element provides accurate response times and resistance to pressure surges.
• Corrosion Resistance: Engineered for use with neutral brine and fresh water, preventing premature fouling in the valve body.
• Field Serviceability: Straightforward mechanical adjustment allows for precise set-point tuning directly on the job site.

What is the maximum working pressure for the Danfoss WVFX-40?
The valve is rated for a maximum working pressure on the water side of 16 bar (232 psi) and a maximum refrigerant side pressure of 26.5 bar (384 psi).

Can this valve be used with sea water applications?
The standard WVFX series is intended for fresh water and neutral brine. For sea water applications, a titanium or specialized alloy version is typically required to prevent salt-water corrosion.

Is the Danfoss 003F124000 a direct substitute for the 003F1240?
Yes, the 003F1240 and 003F124000 are the same technical component and are interchangeable in all 1 1/2" piping specifications.
