Danfoss 003N7006 Valve

The Danfoss 003N7006 is a heavy-duty WVFX 20 water regulating valve engineered specifically for technical refrigeration plants with water-cooled condensers. This pressure-operated component maintains consistent condensing pressure by accurately modulating the flow of fresh water or neutral brine. Built with a robust brass body, the valve features a 3/4" NPT water connection and a 1/4" SAE flare refrigerant connection for seamless integration into standard manifolds. It operates within a control pressure range of 60 to 333 psig, ensuring stability even during significant load fluctuations. Designed to open on rising condensing pressure, the valve is pressure-relieved, meaning variations in water supply pressure will not disrupt the setpoint. With a Kv value of 3.4 m³/h and a maximum working pressure of 232 psig on the water side, this regulator is a staple for contractors prioritizing system longevity and head pressure control in commercial HVACR environments.

Key Benefits:

• Optimized Condensing Pressure: Precisely modulates water flow to keep high-side pressures within spec, regardless of load.
• High Durability Construction: Features a brass valve body and high-grade stainless steel components to resist corrosion in water-cooled applications.
• Versatile Media Compatibility: Suitable for use with fresh water and neutral brine, making it ideal for diverse industrial cooling setups.
• Precise Pressure Response: The bellows element provides immediate response to small pressure variations for superior stability.
• Field Serviceable: Standard flare connections and accessible internals allow for efficient maintenance and cleaning in the field.

Common Questions:

What is the maximum temperature rating for the medium?
The valve is rated for a medium temperature range of -13°F to 266°F, making it suitable for both chilled water and high-temperature condenser loops.

Does water pressure affect the valve setting?
No. The WVFX 20 is pressure-relieved, so fluctuations in your water supply pressure do not affect the opening or closing setpoints of the refrigerant side.

Can this valve be used with flammable refrigerants?
Yes, the design typically allows for use in systems with localized refrigerant circuits, though you should always verify specific ASHRAE safety group compatibility for your installation.
