Danfoss 003N3411 WVFX 20 Water Regulating Valve 3/4" NPT R410A

The Danfoss 003N3411 is a pressure-operated water regulating valve designed for refrigeration systems with water-cooled condensers using R410A refrigerant. This WVFX 20 model provides automatic modulation of cooling water flow to maintain optimal condensing pressure during system operation.

Key Features:

• 3/4" NPT water connection for easy installation
• Control pressure range of 4 to 26 bar for precise regulation
• Kv flow coefficient of 3.4 m³/h for appropriate water flow capacity
• 1/4" SAE flare refrigerant connection for system integration
• Opens on rising condensing pressure for responsive control
• Automatically shuts off water flow when refrigeration system stops
• Compatible with R410A and other HFC, HCFC, and HC refrigerants

This valve maintains consistent condensing pressure by modulating water flow through the condenser based on refrigerant pressure. When condensing pressure rises, the valve opens to increase cooling water flow. When the system shuts down, the valve automatically closes to stop water flow, preventing waste and water hammer. Ideal for commercial refrigeration and air conditioning applications requiring reliable water-cooled condenser control.
