Danfoss wvfx25 Pressure Operated Water Valve 1 Inch 4 to 23 Bar 5.5 M3/h

Product Description

The DANFOSS WVFX25 is a pressure operated water regulating valve designed for use in refrigeration and air conditioning systems. It controls the flow of condenser cooling water based on refrigerant condensing pressure. As condensing pressure rises, the valve opens to allow more cooling water through the condenser. This helps maintain stable system pressures and protects compressors from high-pressure faults. The WVFX25 is built for HVAC-R technicians, refrigeration engineers, and mechanical contractors who need reliable condenser water control in commercial cooling systems. The valve uses a G-thread connection on the water side, sized at 1 inch. On the refrigerant side, it uses a 1/4 inch SAE flare connection with a 6 mm fitting. The control pressure range spans 4 bar to 23 bar, making it suitable for a wide variety of refrigerants and system designs. The Kv flow value is 5.5 cubic meters per hour, allowing adequate water flow for mid-size condensers and cooling circuits. The opening configuration responds directly to rising condensing pressure, which means no separate controller or signal is needed. The valve is self-actuating. This simplifies installation and reduces the number of components in the system. Refrigeration water regulating valves like the WVFX25 are commonly installed on water-cooled condensers in commercial chillers, ice machines, beer coolers, and process cooling equipment. They help reduce water waste by only allowing flow when the system demands cooling. Danfoss is a global leader in refrigeration components, and the WVFX25 reflects their engineering standards for consistent performance in demanding environments. This valve is a direct replacement for systems that specify the WVFX 25 model.

• Opens on rising condensing pressure for automatic, self-actuating water flow control
• 1 inch G-thread water connection with 1/4 inch SAE flare refrigerant port for easy integration
• Wide control pressure range of 4 to 23 bar suits a broad range of refrigerants and system configurations

Product Highlights

The DANFOSS WVFX25 pressure operated water valve provides reliable, self-regulating condenser water control across a wide pressure range. It is a practical solution for water-cooled refrigeration and air conditioning systems requiring precise flow management.
