Product details
Danfoss WVFX 32 Pressure Operated Water Valve | 1 1/4 in
Product Description:
The Danfoss WVFX 32 (003F1232) is a critical component for optimizing the efficiency of water-cooled condensers across the UAE. By sensing the refrigerant pressure, it automatically adjusts the flow of cooling water to maintain a stable condensing pressure, regardless of water temperature fluctuations common in Dubai’s cooling tower systems. Featuring 1 1/4 in (G 1 1/4) threaded connections and a high flow capacity of 11.0 $m^3/h$, it is built to handle the demands of medium-to-large chillers. The valve is pressure-neutralized, ensuring that changes in water pressure do not affect its precise regulation, and its robust design with stainless steel bellows provides long-term reliability against the potentially corrosive water conditions in the UAE.
Key Features & Benefits:
- Energy & Water Savings: Modulates water flow based on actual cooling demand, significantly reducing water consumption in UAE buildings.
- Stable System Performance: Maintains constant condensing pressure, ensuring stable expansion valve operation and cooling capacity in Dubai.
- Large Flow Capacity: Kv value of 11.0 $m^3/h$ makes it suitable for high-load commercial applications in the UAE.
- Wide Adjustment Range: Flexible setting from 4.0 to 17.0 bar, compatible with various HFC and HCFC refrigerants.
- Corrosion Resistance: Designed with high-quality materials to withstand the mineral-rich water found in many UAE cooling systems.

FAQs:
- Q: Is the WVFX 32 (003F1232) suitable for sea water cooling in the UAE?
- A: The standard WVFX is designed for fresh water and neutral brines. For sea water applications in the UAE, the WVS series or specifically coated valves are generally required.
- Q: Can this valve be used with R410A systems in Dubai?
- A: This model is rated up to 26.5 bar on the refrigerant side. For high-pressure R410A systems in the UAE, please verify if the peak condensing pressure stays within this limit; otherwise, the WVFX high-pressure version may be needed.
- Q: How does this help with UAE’s green building regulations?
- A: By preventing excess water flow when the cooling demand is low, it directly contributes to water conservation and reduces the energy used by water pumps in UAE facilities.
