Danfoss 003N8025 Valve

The Danfoss 003N8025 is a high-performance pressure operated water valve designed specifically for professional HVACR applications. Engineered as a WVFX 25 model, this valve features a 1-inch NPT connection and is built to regulate water flow in refrigeration plants with water-cooled condensers. It effectively maintains constant condensing pressure by modulating the water flow, automatically shutting off during system standby to conserve resources. This unit serves as the direct replacement for 003N8005 and the V46AD-6, offering a seamless swap for technicians upgrading aging liquid cooling infrastructure.

Constructed with a rugged brass body and a 36-inch capillary tube, the 003N8025 provides a wide control pressure range of 60 to 338 psig (4 to 23 bar). Its self-acting design requires no external power, making it a reliable solution for remote installations. With a flow coefficient (Cv) of 6.4 gal/min and a maximum working pressure of up to 380 psig on the water side, this water regulating valve ensures precise modulation even in high-demand industrial environments. The inclusion of a 1/4-inch flare nut with a Schrader depressor on the condenser side connection allows for simplified pressure sensing and system diagnostics.

• Precise Pressure Regulation: Maintains stable condensing temperatures to optimize compressor efficiency and system longevity.
• Universal Compatibility: Designed for use with all common non-corrosive refrigerants, including HFC and HCFC blends.
• Durable Brass Construction: High-grade materials ensure resistance to internal scaling and external environmental wear.
• Simplified Maintenance: Featuring a pressure balanced valve design, it remains insensitive to variations in water inlet pressure, reducing the need for constant recalibration.
• Easy Installation: The 36-inch capillary provides the flexibility needed for optimal sensor placement in crowded mechanical rooms.

• What does "opens on rising pressure" mean for my system? In this direct-acting configuration, the valve increases water flow as the head pressure rises, effectively removing heat and stabilizing the cycle.
• Is this valve compatible with seawater applications? This specific brass model is intended for standard fresh-water cooling; for saltwater or brackish environments, a specialized bronze or monel version is typically required.
• How do I adjust the setpoint? The pressure range is manually adjustable via the top-mounted spring housing to match the specific operating requirements of your refrigerant.
