Danfoss EV220B 25 Normally Closed Solenoid Valve | G 1 | 032U8125

Product Description: The EV220B (032U8125) is engineered for efficiency and durability in high-demand environments. In the UAE—where precise water management in commercial buildings and industrial plants is critical—this valve’s “Normally Closed” design ensures that flow is securely shut off when the coil is de-energized. With its large 25mm orifice and a $K_v$ value of $11\ m^3/h$, it handles significant volumes of water or neutral liquids. The EPDM seals are specifically designed for water applications, providing excellent resistance to heat and aging, while the built-in pilot filter ensures the valve remains operational even in systems with occasional sediment or debris.

Key Features & Benefits:

• Normally Closed (NC) Function: Automatically shuts off flow upon power loss, providing essential safety and control for UAE water systems.
• Large Flow Capacity: The 1-inch ($G\ 1$) port offers a high flow rate ($11\ m^3/h$), ideal for main water lines and industrial cooling loops.
• Integrated Pilot Filter: Protects the sensitive pilot orifice from clogging, a vital feature for maintaining uptime in Middle Eastern utility networks.
• Water Hammer Damping: Optimized diaphragm design ensures soft closing, significantly reducing pressure surges that can damage UAE piping infrastructure.
• Robust Brass Body: Provides the mechanical strength required for high-pressure industrial applications up to 16 bar.

FAQs:

• Q: Is the 032U8125 suitable for drinking water in Dubai?
• A: Yes, the EPDM (EPD) version is designed for water and is widely used in potable water and heating systems across the UAE.
• Q: Does this valve require a minimum pressure to open?
• A: Yes, as a servo-operated valve, it requires a minimum differential pressure of 0.3 bar to lift the diaphragm and allow full flow.
• Q: Can I use this for oil-based systems?
• A: No, EPDM seals will swell and fail if exposed to oil. For oil applications in the UAE, the FKM (Viton) version of the EV220B should be used.
